Some fisheries managers believe\nthat reservoir drawdown would help restoration efforts for depleted upriver stocks of Snake River\nchinook (Oncorhynchus tshawytscha) and sockeye salmon (O. nerka). The drawdown would\nsimulate a free-flowing river, which would theoretically decrease downstream travel time and\nthus increase the survival of juvenile salmonids (Oncorhynchus spp.).\nSeveral drawdown scenarios have been proposed for selected Columbia and Snake River\nreservoirs. Each involves the operation of reservoirs at or below minimum operating pool\n(MOP) for several months. Any extended drawdown at or below MOP would be an\nunprecedented event in the operation of these reservoirs and would have undetermined impacts\non reservoirs and their associated riverine ecosystems. For Lower Granite Reservoir, a\ndrawdown to depths of 10, 13, and 16 m below MOP during the spring and summer juvenile\nsalmonid outmigration periods (April-August) has been suggested. A drawdown to depths of\n33.5 to 35 m below MOP to simulate a free-flowing river has also been suggested.\nTo better understand possible changes that may occur in Lower Granite Reservoir as a\nresult of a drawdown, we began limnological studies to document pre-drawdown conditions.\nThe goals of these studies were to document physical, chemical, and biological parameters\nexisting within the reservoir before a drawdown occurs. Our research commenced in\nMarch 1994 and continued through October 1995. We concentrated on potential impacts of\ndrawdown in three selected shallow-water habitats of the reservoir.\nIn a previous report, we described temporal changes observed in benthic invertebrate\npopulations inhabiting the soft substrate in these shallow-water habitats. This report covers the","remaining aspects of these investigations, mainly temporal changes in physical characteristics of\nthe water column, water quality, chlorophyll concentrations, zooplankton populations, and\nsediment composition.\nSampling areas were located on the upstream end of the reservoir near Silcott Island, at\nmid-reservoir near Centennial Island, and near the terminus of the reservoir about 3 km upstream\nfrom Offield Landing. At each area, samples for physical, chemical, and biological parameters\nwere collected from the water column at approximately the 18-m depth contour, and sediment\nsamples were collected from along the 3-, 9-, and 18-m depth contours.\nWater samples were collected biweekly from April through September and monthly for\nthe rest of the year except during December and February. Sediment samples were collected\nquarterly through the year. Water temperature, dissolved oxygen, conductivity, and pH were\nmeasured at 1-m depth intervals through the water column. Water transparency and depth of the\neuphotic zone were also measured, and water samples from 1-, 7-, and 15-m depths were\ncollected for turbidity measurements.\nVarious water chemistry parameters were also examined, with collected water samples\nstored in the dark on ice and transported within 24 hours to the State of Washington Water\nResearch Center for analyses of nitrogen, phosphorus, cations, anions, silica, and alkalinity.\nComposite water samples were collected for analysis of chlorophyll concentrations, and\nconcentrations of chlorophyll a were used as an index of phytoplankton biomass. Because a\nlarge portion of the phytoplankton present in the water column is often less than 25-um in size,\nchlorophyll concentrations were determined for both an unfiltered water sample and a sample\nfiltered through a 25-um net. Chlorophyll a, b, and C and pheophytin a concentrations were\ndetermined using the cold-acetone extraction and spectrophotometric method.\niv","Zooplankton samples were collected with a plankton net and preserved and stained in the\nfield. Analyses for zooplankton species composition and numerical density were conducted\nunder contract to Beaver Schaberg Associates, Inc. Sediment samples were collected using a\nPonar grab, and analyses for particle grain size, soil classification, and percent volatile solids\nwere conducted under contract.\nSurface-to-bottom water quality profiles for water temperature, dissolved oxygen,\nconductivity, and pH showed little stratification of the water column at the three shallow-water\nareas sampled. Temporal changes in water temperature and dissolved oxygen showed expected\nseasonal changes during the study period, with no apparent difference among sampling areas.\nDissolved oxygen was generally above 85% saturation throughout the study, except near the\nbottom during August and September 1994, when there was evidence of oxygen depletion.\nIn 1994, a low-flow drought year, water temperature was higher than in 1995, an average-to-high\nflow year. Conductivity was lowest in the summer and highest in the winter, whereas pH values\nwere highest in the summer and lowest in the winter.\nAt all three sampling areas, depths of euphotic zone were shallow through the spring and\nearly summer, then increased in the summer following the spring freshet period (range 1 to 8 m).\nChanges in euphotic depth were positively correlated to depth of Secchi-disk transparency and\ninversely correlated to turbidity measurements.\nIn general, there were only slight differences among sampling areas and depths for the\nvarious nutrient parameters and alkalinity. Seasonal trends for each of these parameters were\nobserved, with highest concentrations during winter and lowest concentrations during summer.\nMonochromatic chlorophyll a concentrations (corrected for pheophytin) were variable\nbetween sampling areas and through time. Concentrations from the fraction of the sample less\nV","25 um in size generally comprised more than 50% of the measured chlorophyll a. Monthly\nmean monochromatic chlorophyll a values for the 3 sampling sites ranged from 0.3 to 19.2\nmg/m3. Zooplankton populations were dominated by rotifers, and to a lesser extent, cladocerans\nand copepods: 31 species of rotifers and 16 species of cladocerans were identified.\nThere were apparent differences in sediment characteristics between sampling areas and\nbetween depths within each sampling area. However, there was little indication of temporal\nchange in sediment characteristics among sampling areas and depths. Sand and fines were more\ncommon than gravel at all three sampling areas, and median grain size varied between sampling\nareas and depths. Percentages of silt/clay and volatile solids were generally higher at Centennial\nIsland than at the other two sampling areas.\nIn summary, water quality parameters sampled in the shallow-water sites within Lower\nGranite Reservoir exhibited some obvious seasonal changes, with little stratification of the water\ncolumn. Seasonal trends for various nutrient parameters, alkalinity, and conductivity showed\nhighest concentrations during winter and lowest concentrations during summer, whereas pH\nvalues were highest during winter and lowest during summer. Concentrations of\nmonochromatic chlorophyll a varied throughout the year and between sites with no obvious\nseasonal trend. The zooplankton population was dominated numerically by rotifers and to a\nlesser extent, cladocerans and copepods. There was little indication of temporal change in\nsediment characteristics among sampling areas and depths.\nvi","CONTENTS\nEXECUTIVE SUMMARY\niii\nINTRODUCTION\n1\nMETHODS\n2\nStudy Area\n2\nWater Column Profiles\n4\nTransparency, Turbidity, and Euphotic Depth\n4\nNutrients\n5\nAlkalinity\n5\nChlorophyll\n5\nZooplankton\n7\nSediment\n8\nStatistical Analyses\n8\nRESULTS\n9\nWater Column Profiles\n9\nTransparency, Turbidity, and Euphotic Depth\n15\nNutrients\n18\nAlkalinity\n18\nChlorophyll\n18\nZooplankton\n25\nSediment Composition\n32\nDISCUSSION\n39\n42\nCONCLUSIONS\nACKNOWLEDGMENTS\n43\nREFERENCES\n44\nAPPENDIX A: Chlorophyll methodology\n47\nAPPENDIX B: Data tables\n55\nvii","INTRODUCTION\nHistorical estimates of the number of adult salmon in the Columbia River Basin\nbefore hydroelectric dams were built ranged from 8 to 16 million, but present estimates\nrange from 2 to 2.5 million (COE 1992a). Snake River sockeye salmon (Oncorhynchus\nnerka) were listed as endangered in 1991 under the Endangered Species Act of 1973, and\nspring/summer and fall chinook salmon (O. tshawytscha) were listed as threatened\nin 1992. A \"Salmon Summit\" was held in 1990 and 1991 among regional fishery and\npower agencies, tribes, and river users to develop a restoration plan for declining salmon\nruns. One suggestion was to draw the river water level down in one or several reservoirs\nin the Snake and Columbia Rivers during juvenile salmon migration to increase\ndownstream water velocity and thus theoretically decrease the travel time for salmon\nsmolts migrating to the ocean.\nA 1-month test drawdown to lower the water level to elevation 212 m (695 ft) in\nLower Granite Reservoir occurred during March 1992 as part of an extensive effort to\nevaluate possible effects of a long-term reservoir drawdown. Following the test\ndrawdown, various limnological studies of Lower Granite and other downstream Snake\nRiver reservoirs commenced in an effort to document conditions existing prior to other\npossible reservoir drawdowns (Ledgerwood et al. 1996, Bennett et al. 1997, Juul 1997).\nIn March 1994, we began a multi-year limnological study of shallow-water habitats in\nLower Granite Reservoir. A drawdown was planned for Lower Granite Reservoir from\nApril to June 1996. Initially our study was planned for 5 years to document conditions\nduring the 2 years prior to drawdown, the 1 year during drawdown, and the 2 years after\ndrawdown. However, plans for drawdown of Lower Granite Reservoir have been\ncanceled or delayed; thus sampling of pre-drawdown conditions ceased in October 1995.\nThe goal of our study was to document existing physical, chemical, and biological\nfactors of the reservoir to provide a more thorough understanding of the dynamics of this\ncomplex reservoir ecosystem, including temporal changes to compare conditions prior to\ndrawdown with those that prevail during and after drawdown. Three shallow-water\nhabitats were selected as sampling areas: one in the upstream, one in the middle, and one\nin the downstream portion of Lower Granite Reservoir. Measurements were made of\nphysical parameters: water temperature, dissolved oxygen, conductivity, pH, euphotic\ndepth, Secchi disc transparency, and turbidity. Sediment composition and chemical\nparameters including nitrogen, phosphorus, cations, anions, silica, and alkalinity were\nanalyzed. Biological parameters examined were chlorophyll a concentrations and\nzooplankton populations. These locations were chosen to provide an overall picture of\nthe limnological conditions in the reservoir. This report covers results of our\ninvestigations of pre-drawdown limnological conditions in these habitats between\nMarch 1994 and October 1995 and supplements our earlier report on benthic invertebrate\npopulations in the same habitats of the reservoir from the same period (Pool and\nLedgerwood 1997).","METHODS\nStudy Area\nLower Granite Reservoir was created in 1975 when Lower Granite Dam was\nconstructed for production of hydroelectric power, improved navigation, irrigation, and\nrecreation (COE 1992b). The reservoir is located in southeastern Washington and\nwestern Idaho near Clarkston, Washington, and Lewiston, Idaho, and extends upstream\n61.8 km from the dam on the Snake River to Asotin, Washington, and 7.3 km upstream\nfrom the confluence of the Snake and Clearwater Rivers (COE 1992b). Following\nconstruction of the dam, the hydrography of this segment of the Snake River changed\nfrom free-flowing river to a pool with a maximum depth of 35 m (Dorband 1980).\nWe selected three shallow-water areas in Lower Granite Reservoir for the study\n(Fig. 1). These areas were at River Kilometer (RKm) 212 near Silcott Island, at\nRKm 193 near Centennial Island, and at RKm 177 near Offield Landing. The sampling\narea near Silcott Island is located about 39 km upstream from Lower Granite Dam, about\n11 km downstream from the confluence of the Snake and Clearwater Rivers at Lewiston,\nIdaho, and Clarkston, Washington. Centennial Island was created near the middle of the\nreservoir in 1989 as a result of dredging activity by the U.S. Army Corps of Engineers\n(COE 1992b) and is about 20 km upstream from the dam. The Offield area was about\n4 km upstream from Lower Granite Dam (RKm 173). At all three areas, most\nlimnological samples were collected biweekly from April through September and\nmonthly during the rest of the year, except in December 1994 and February 1995.\nSediment samples were collected quarterly, and benthic invertebrate samples were\ncollected monthly except during April and December 1994 and February 1995 (Pool and\nLedgerwood 1997).\n2","WA\nLower Granite Dam (RKm 173)\nN\nOffield (RKm 177)\nK\nID\nCentennial Island\n(RKm 193)\nSilcott Island\nClearwater\n(RKm 212)\nRiver\nClarkston\nLewiston\nAsotin\nFigure 1. Location of Lower Granite Reservoir and locations of three selected shallow-\nwater sampling areas.\n3","Water Column Profiles\nSurface-to-bottom water-column profiles for measurements of water temperature,\ndissolved oxygen, conductivity, and pH were obtained using a multiparameter Hydrolab\nSurveyor submersible probe and data logger. The water-column profiles were obtained\nfrom a boat anchored or drifting along the 18-m depth contour, and data were recorded at\n1-m depth intervals from the surface to a depth of 15 m and at 0.5 m above the bottom.\nThe percent saturation of dissolved oxygen for each water column profile was calculated\nusing the following formula (Wetzel and Likens 1991):\nPercent saturation =\n100\nX\nS\nB\nwhere\nDO\n= dissolved oxygen (mg/L)\nP\n= measured barometric pressure (mm Hg)\n= oxygen solubility (mg/L) at 100% saturation at standard pressure in\nS\nmoist air\n= 760 mm Hg which is standard barometric pressure at sea level\nB\nTransparency, Turbidity, and Euphotic Depth\nA 20-cm-diameter black and white Secchi disc was used to measure depth of\nwater transparency (Goldman and Horne 1983, Lind 1985, Wetzel and Likens 1991).\nThe Secchi disc was lowered into the water column in the shadow of the boat until it\ndisappeared, then the depth of disappearance was recorded.\nTurbidity is a measurement of suspended matter, which has a tendency to reduce\nand scatter sunlight the water receives (Welch 1952, Lind 1985, Wetzel and\nLikens 1991). Water samples for turbidity measurements were collected from 1-, 7-, and\n15-m depths using a 4-L Van Dorn sampler. From March through July 1994, turbidity\nwas measured in the field using an HF Instruments model DRT15 turbidimeter, and\nthereafter, using a Hach model 2100P turbidimeter.\n1 Reference to trade names does not imply endorsement by the National Marine Fisheries\nService, NOAA.\n4","Beginning in mid-May 1994, we used two KAHLSICO underwater irradiameter\nprobes to determine the depth of the euphotic zone. The euphotic zone was defined as a\nwater layer receiving enough sunlight for photosynthesis of chlorophyll pigments and\npopulation growth of phytoplankton (McKee and Wolf 1963, Schwoerbel 1987,\nMoss 1988). To obtain the measurement, we lowered one irradiameter probe to the depth\nat which the reading was 1% of the partial energy value from available sunlight at the\nwater surface, as indicated by the second probe, which was held just beneath the water\nsurface (Lind 1985, Kimmel et al. 1990) (Gerald J. Kahl, KAHLSICO International\nCorp., P.O. Box 947, El Cajon, CA 92022-0947, Pers. commun., July 1995). The depth\nto which the first irradiameter probe was lowered defined the depth of the euphotic zone,\nand thus the level at which subsequent water samples were taken for zooplankton and\nchlorophyll analyses.\nNutrients\nWater samples for nutrients were collected from 1-, 7-, and 15-m depths using a\n4-L Van Dorn sampler along the 18-m depth contour at each sampling area. Samples\nwere stored in the dark on ice until transport and were transported on ice within 24 hours\nof collection. Analyses were conducted under contract to the State of Washington\nResearch Center (WRC), Washington State University, Pullman, WA (Dr. Steve Juul,\npoint of contact). Samples were analyzed for nitrogen, phosphorus, and silica; the cations\nsodium, potassium, calcium, and magnesium; and the anions chloride and sulfate.\nAlkalinity\nWater samples for measurements of alkalinity, like those for nutrient analyses,\nwere obtained using a 4-L Van Dorn sampler, with samples taken from 1-, 7-, and 15-m\ndepths along the 18-m depth contour at each sampling area. Alkalinity measurements\nwere taken while in the field using a chemical titration kit (LaMotte model WAT-MP-\nDR).\nChlorophyll\nChlorophyll a concentrations were used as a crude index of phytoplankton\nbiomass (APHA 1992). Laboratory analyses of chlorophyll a concentrations in samples\nincluded interference of accessory pigments such as chlorophyll b and pheophytin a\n(APHA 1992). Therefore, our laboratory procedures included analyses for concentrations\nof monochromatic chlorophyll a (pheophytin-corrected), pheophytin a, and trichromatic\nchlorophyll a, b, and C.\nWater samples for analysis of chlorophyll were generally collected from a boat\ndrifting along the 18-m depth contour at each sampling area. Initially samples were\n5","collected from the water column from the surface to a depth of 15 m. In April 1995, we\nmodified this procedure to collect samples from 0.5 m deeper than the depth of the\neuphotic zone, which had been previously established using an irradiameter. In April,\nJuly, and October 1995, an additional set of composite samples was collected from the\nwater surface to the 15-m depth in order to compare chlorophyll results with those\nobtained from the fixed 0- to 15-m depth samples and the variable-depth euphotic zone\nsamples.\nEach composite sample was obtained with a 38- or 50-mm (inner diameter) hose.\nA rope and weight were attached to the distal end of the hose, which was deployed\nvertically to a specified depth in the water column (Goldman and Horne 1983). After\ndeployment, the surface end of the hose was capped shut and the distal end retrieved from\ndepth using the attached rope. The retrieved sample was then emptied into a clean 19-L\nbucket for mixing and subsampling. Two subsamples were obtained from the bucket and\nstored in the dark on ice in brown, opaque plastic bottles.\nBecause a large portion of the phytoplankton in water is often less than 25 um in\nsize (Lieberman 1992), two additional subsamples were obtained from the bucket after\nfiltering through a stoppered 25-um plankton net. Beginning in March 1995, we\nmodified the general procedure to obtain two independent subsamples from the reservoir\nusing one unfiltered subsample and one filtered subsample from each 19-L sample.\nFrom March to June 1994, chlorophyll samples were taken to WRC for analysis,\nand thereafter, samples were transported to and analyzed at our laboratory. The\ncold-acetone extraction and spectrophotometric method was utilized by both laboratories\n(APHA 1992). Samples were suction filtered in subdued light through 47-mm Whatman\nGF/C glass fiber filters (APHA 1992). Depending on turbidity, up to 1000 mL of water\nsamples were filtered. To avoid damaging delicate phytoplankton, vacuum pressure\nduring filtration was not allowed to exceed 25 cm Hg (Wetzel and Likens 1991).\nSamples on filters were stored in the freezer prior to extraction and spectrophotometric\nanalysis (APHA 1992). Complete details of the collection and laboratory methods for\nchlorophyll analyses are presented in Appendix A.\nCalculations for concentrations of monochromatic chlorophyll a and pheophytin a\nand trichromatic chlorophyll a, b, and c, and for deterioration ratio were derived from the\nformulas given by APHA (1992). Calculations for monochromatic chlorophyll a\nincluded correction for pheophytin a, a degradatory pigment which absorbs wavelengths\nsimilar to those absorbed by chlorophyll a.\nAnalyses of chlorophyll concentrations collected from the three selected\nshallow-water habitats were separated into two groups due to differences in\nmethodologies (i.e., the depth from which samples were taken). The first group included\nsamples collected from the water surface to the 15-m depth, and the second group\nincluded samples collected from 0.5 m below the euphotic zone. The second group of\nsamples did not include chlorophyll concentrations from depths beneath the euphotic\n6","zone; therefore, variations in chlorophyll concentration between 1994 and 1995 were not\nentirely comparable. Mean values of the two replicate samples for monochromatic\n(pheophytin-corrected) chlorophyll a concentrations were presented.\nZooplankton\nZooplankton samples were collected using an 80-um Wisconsin-style plankton\nnet with a 15-cm-diameter mouth. Samples were collected at approximately the 18-m\ndepth contour at each sampling area. Three vertical tows were made by lowering the net\nto the 15-m depth, then retrieving it by hand at a vertical speed of about 0.5 m/second\n(APHA 1992). Beginning in April 1995, sample depth was adjusted to the depth of the\neuphotic zone plus 0.5 m (the euphotic zones having been previously determined with an\nirradiameter). In April, July, and October 1995, additional zooplankton samples were\nobtained from the 15-m depth to compare the two sampling methods. Zooplankton\nsamples were poured and rinsed with distilled water into 250-mL plastic bottles and\npreserved and stained with addition of Lugol's iodine solution; from 3 to 7 mL of the\niodine solution was added to the sample depending on the final volume after rinsing.\nAnalysis of zooplankton samples for species composition and numerical density\nwere conducted under contract to Beaver Schaberg Associates, Inc., Shaker Heights, Ohio\n(Dr. John Beaver, point of contact). Mean densities of zooplankton from three replicate\nsamples at each sampling area were used for data analysis and presentations. We also\nassigned the National Oceanographic Data Center (NODC) taxonomic codes (version 7.0)\nto each organism based on its taxonomic classification. 2 Taxonomic information for each\norganism was contained in the hierarchy of each code and allowed data for organisms to\nbe grouped and summed into a desired taxonomic classification.\nComputer programs were utilized to combine tallies of organisms into five\npossible taxonomic levels. For example, tallies for Diacyclops thomasi and Cyclopoida\nwere combined into the order Cyclopoida, and total densities for this order of copepods\nwere then compared with those of other orders of copepods. Mean densities were\ncalculated for each grouped or ungrouped taxon/category of zooplankton for comparisons\namong sampling areas and dates. Density was expressed as number of organisms/L.\n2\nNational Oceanographic Data Center, NOAA/NESDIS E/OC1, SSMC3, Room 4649,\n1315 East-West Highway, Silver Spring, MD 20910-3282.\n7","For analysis, zooplankton data were separated into two groups, one for samples\ncollected from a depth of 0-15 m, and one for samples collected from a depth of 0 m to\n0.5 m below the euphotic zone. Zooplankton also live below the euphotic depth and\nmigrate vertically for feeding. Therefore, conclusions regarding seasonal variation in\nzooplankton species composition and numerical density of the two groups were limited.\nSediment\nSoft-substrate sediment samples were obtained using a Ponar grab measuring\nabout 0.05 m². This was the same sampler used for collecting benthic invertebrate\nsamples (Pool and Ledgerwood 1997). Sediment samples were collected in May, August,\nand November 1994 and January, April, July, and October 1995. These samples were\ncollected from the same stations established along four transects in each sampling area\nfor our sampling for benthic invertebrate populations (Pool and Ledgerwood 1997). For\nsediment samples, we used only the middle upstream transect along the 3-, 9-, and 18-m\ndepth contours from each sampling area. In July 1995, sediment samples were collected\nfrom all 36 benthic invertebrate stations; however, only samples from the middle\nupstream transect at each sampling area were included for this analysis.\nSediment samples were emptied from the Ponar grab onto a metal tray: a ladle\nwas used to transfer about 0.5 L of sediment from the tray to a plastic zippered bag. The\nbags were then sealed and stored in the dark and kept cool. Samples were taken to the\nU.S. Army Corps of Engineers North Pacific Division Materials Laboratory, Troutdale,\nOregon (Jim Hinds, point of contact), for analyses, including particle grain size, soil\nclassification, and percent volatile solids.\nStatistical Analyses\nThe study design was to compare pre- and post-drawdown limnologeal\nparameters. Abrupt termination of the study in October 1995 precluded detailed\nstatistical comparisons because drawdown did not occur. One-way analysis of variance\nwas used to compare possible differences among sample sites, depths, and dates. For\nthese rather primitive comparisons, we assumed there was no interaction between sites\nand dates. For brevity, when differences in sites, dates, or depths of samples were not\nsignificant (P< 0.05), we used the pooled mean value + the standard error of the mean in\nthe text. Detailed data for each parameter are presented in tables, figures, and appendixes\nfor each sampling area, depth, and date.\n8","RESULTS\nA total of 30 sampling trips were made to the reservoir, with each trip generally\nrequiring 3 to 4 days for sample collection. Data summaries for all parameters studied\nare presented in Appendix B. In addition, data from all samples were compiled into a\nrelational database (Microsoft Access version 2.0). 3 Electronic formats of the data are\navailable upon request.\nWater Column Profiles\nTemporal changes in water temperature, dissolved oxygen, conductivity, and pH\nduring the study period showed seasonal changes and little stratification of the water\ncolumn in the shallow-water habitats studied (Figs. 2-6). There were significant\ndifferences among sampling areas (P > 0.05) and the water column appeared well mixed\nthroughout the year, with the possible exception of August to September 1994.\nIn 1994, a low-flow drought year, water temperatures were considerably higher\nthan in 1995, an average-to-high-flow year. For instance, the highest mean\nsurface-to-bottom temperature in 1994 was 23.0°C, while in 1995 the highest mean was\nonly 19.9°C (Fig. 2). Throughout the study period, the lowest mean surface-to-bottom\ntemperature was 3.3°C. At no time during our sampling did we record a thermocline, or\nvertical change in water temperature, that exceeded 1°C per meter (Moss 1988). The\ngreatest thermal stratification within our sampling areas occurred in July and\nAugust 1994, with a change of about 3°C, and the least thermal stratification was seen\nduring the winter months, with a change of about 0.5°C (Appendix Table B1).\nThere were only minor differences in dissolved oxygen concentrations at\nsampling areas between 1994 and 1995 (mean 10.0 + 0.1 mg/L) (Fig 3). Generally, mean\nsurface-to-bottom dissolved oxygen concentrations were highest during winter and lowest\nduring summer at each sampling area. During August and September 1994, the period of\nwarmest water, the percent saturation of dissolved oxygen at the water surface was over\n95% at all sampling areas (Fig. 4). However, the percent saturation of dissolved oxygen\nnear the bottom (down to the 22-m depth) dropped to about 5 mg/L, approaching\nconcentrations known to be stressful and fatal to fish (Welch 1952, McKee and\nWolf 1963) (Appendix Table B1). These dangerously low levels of dissolved oxygen\nnear the bottom at our sampling areas were not recorded in 1995.\n3 Included in the database are results of limnological sampling conducted in John Day Reservoir\non the Columbia River during a similar time period (Lyle Gilbreath, FE Project Leader).\n9","Silcott Island\n0\n5\n10\n15\n20\nTemperature\n25\n(C)\n3\nIsland\n5\n7\n9\n11\n10\n13\n15\n15\n17\n20\n19\n25\n21\n23\nOffield\n5\n10\n15\n20\n25\nVertical\nFigure\n2.\n10","Silcott Island\n0\n5\n10\n15\n20\nDissolved\nOxygen\n25\n(mg/L)\n5\nCentennial Island\n6\n0\n7\n5\n10\n8\n15\n9\n20\n10\n25\n11\n12\nOffield\n0\n13\n5\n10\n15\n20\n25\nFigure 3. in Vertical Lower profiles Granite of temporal changes in dissolved\nwater column.

Surface-to-bottom pH profiles at each sampling area\nwere also similar throughout the study period (Fig. 6).\nTransparency, Turbidity, and Euphotic Depth\nThe amount of sunlight penetrating the water column and the depth of sunlight\npenetration were estimated using Secchi disc turbidimeters and irradiameters,\nrespectively. There was good temporal correlation between the various estimations of\nlight penetration at all sampling areas (Appendix Tables B2 and B3).\nBoth Secchi disk transparency and estimates of euphotic depth (obtained\nbeginning in mid-May 1994) increased through the spring and summer each year (Fig. 7).\nMaximum values were recorded in November 1994, with transparency at about 3 m and\neuphotic depth at about 8 m. Minimum values were recorded in May 1995, with\ntransparency at about 0.3 m and euphotic depth at about 1 m. There were no significant\ndifferences among sampling areas in either Secchi disk transparency (P= 0.714) or\neuphotic depth (P= 0.698).\nTurbidity values were generally similar among sample areas and depths with\nsome notable exceptions (mean 10 NTU + 1.6) (Fig. 8). Major spikes in turbidity\noccurred (> 40 NTU) at the 5-m depths during May and June 1994 at Centennial Island\nand Offield, but not at Silcott Island. Similar spikes occurred in May 1995 at all sites and\ndepths. A final peak in turbidity value was recorded throughout the water column at\nSilcott Island in August 1995, but this trend was not seen at the downstream sampling\nlocations.\n15","Silcott Island\n0\nCentennial Island\n1\nOffield\n2\n3\n4\n5\n6\n7\n8\n9\n0.0\n0.5\n1.0\n1.5\n2.0\n2.5\n3.0\n3.5\n1994\n1995\nFigure 7.

Temporal and\nseasonal changes for each parameter and sample area were evident (Figs. 9-13).\nConcentrations generally declined during spring, were low during summer, increased\nthrough fall, and remained high over winter. There were no apparent differences among\nsampling areas or depths for the various parameters. Mean values were as follows: 0.59\nmg-N/L total nitrogen, 0.29 mg-N/L nitrite + nitrate, 0.03 mg-N/L ammonia, 0.02 mg-\nP/L total phosphorus, 0.02 mg-P/L orthophosphate, 13.9 mg/L sodium, 2.3 mg/L\npotassium, 16.4 mg/L calcium, 6.5 mg/L magnesium, 7.3 mg/L chloride, 19.4 mg/L\nsulfate, and 16.5 mg/L silica.\nAlkalinity\nResults of alkalinity analyses are presented for each sampling area, date, and\ndepth in Appendix Table B5. There were no apparent differences in alkalinity among\nsampling sites or depths, but there were seasonal and temporal changes similar to those\nseen in nutrients: alkalinity generally declined during spring, was low during summer,\nincreased through fall, and remained high during winter (mean 69.8 mg CaCO/L + 2.8)\n(Fig. 14).\nChlorophyll\nMonochromatic chlorophyll a concentrations (pheophytin-corrected) generally\nfollowed similar patterns at sampling sites in all three areas (Silcott Island, Centennial\nIsland, and Offield) throughout the study period (Table 1, Fig. 15). Concentrations were\nvariable with no obvious seasonal trends between years, although a change in sampling\nmethods that occurred in April of 1995 may have masked possible trends. Overall,\nphytoplankton less than 25 um in size contributed to more than 50% of the measured\nchlorophyll a during both years of study, regardless of sampling methods.\nConcentrations of pheophytin and trichromatic chlorophyll a, b, and C are presented in\nAppendix Table B6.\nFrom March 1994 through March 1995, highest concentrations of chlorophyll a\nwere observed during June, July, and August with most values exceeding 5 mg/m³\n(Fig. 15). Mean chlorophyll a values for all three sites combined during this period\nranged from 0.5 to 12.3 mg/m³, with an overall mean of 4.0 mg/m³.\nChlorophyll a values for the period April through October 1995 were markedly\ndifferent from those of the previous year. Highest chlorophyll a values in 1995 were\nobserved during the week of 5 April (mean 17.3 mg/m3. This sample period was unique\nin that it was one of the few instances where we sampled a phytoplankton bloom near\n18","Ammonia\nSilcott Island\n1.6\nNitrite + nitrate\n1.4\nTotal N\n1.2\n1.0\n0.8\n0.6\n0.4\n0.2\n0.0\nCentennial Island\n1.6\n1.4\n1.2\n1.0\n0.8\n0.6\n0.4\n0.2\n0.0\nOffield\n1.6\n1.4\n1.2\n1.0\n0.8\n0.6\n0.4\n0.2\n0.0\n1994\n1995\nFigure 9.

Pheophytin levels on this date were low (mean 3.19 mg/m3), indicating\nthat little degradation of chlorophyll a had occurred. After this sample date, chlorophyll\na levels generally declined through the spring and summer except for another small peak\nin late August. Mean chlorophyll a values for all three sites combined during this period\nranged from 0.3 to 19.2 mg/m³, with an overall mean of 3.2 mg/m³.\nZooplankton\nZooplankton populations at the three sampling areas were dominated by 31\nspecies of rotifers, 16 species of cladocerans, and 7 taxa/categories of copepods (Table 2).\nSpecies composition and numerical densities of zooplankton are presented in\nAppendix Table B7. Details of taxonomic groupings and electronic formats of the data\nare available upon request.\nNumerically, highest mean zooplankton densities (organisms/L) occurred for\nrotifers (33.6/L), cladocerans (7.2), and copepods (4.6/L)(Fig. 16). Three numerically\ndominant rotifers were Keratella cochlearis (27.5/L), Polyarthra vulgaris (25.6./L), and\nSynchaeta pectinata (22.2/L)(Fig. 17). An obvious peak in rotifer density occurred in\nMay 1995 at Silcott Island and in early August 1995 at Offield. Three numerically\ndominant cladocerans were Daphnia retrocurva (9.1/L), Bosmina longirostris (6.9/L),\nand D. thorata (4.3/L)(Fig. 18). Generally, unidentified nauplii dominated the total\ncopepod population at all three sampling areas, especially during population spikes (mean\nnauplii density, 405/L)(Fig. 19). In late June at Silcott Island, both the copepod nauplii\nand cyclopoids contributed to the total copepod population peak. Temporally, copepod\npopulations appeared highest during late spring and again in late summer. Ostracods\nwere observed only in one sample at Offield in October 1995 (0.07/L).\nIn analyses of the three double samples taken in April, July, and October 1995, we\nobserved differences between sampling methods for zooplankton concentrations (i.e.,\nsamples taken from a depth of 0.5 m below the euphotic zone and those taken from a\ndepth of 0-15 m) (Table 3). At Silcott Island and Centennial Island in 1995, mean rotifer\ndensities from 0.5 m below the euphotic zone were higher than those from the 0- to 15-m\nsample depth in April and July, but the opposite was observed in October. At all three\nsampling areas and all three test dates, mean densities of cladocerans and copepods were\nless than 2.5/L using either sampling method.\n25","Table 2.

However, there were\nobvious differences in sediment composition among sampling areas and between depths\nwithin sampling areas.\nGravel (grain sizes 75 to 4.75 mm) was common at Offield, where the percentages\nranged from 0 to 33.2 for all three sample depths (Figs. 20-22). However, gravel was\npresent only once in Centennial Island sediment samples and was absent in all Silcott\nIsland sediment samples. Sand (median grain sizes 4.75 to 0.074 mm) and fines (grain\nsizes < 0.074 mm) were more abundant than gravel at all three sampling areas.\nRespective mean percentages of sand at the 3-, 9-, and 18-m depths were 36.2, 50.4, and\n90.4 at Silcott Island; 78.5, 13.4, and 10.7 at Centennial Island; and 32.9, 17.2, and 18.8\nat Offield.

Juul (1997) found that many of the chemical and biological\ncharacteristics of Lower Snake River reservoirs were directly related to hydrologic and\nphysicochemical properties of the Snake and Clearwater Rivers. Lower Granite\nReservoir, situated immediately downstream from the confluence of the Snake and\nClearwater Rivers, is greatly influenced by interannual differences in discharges from\nthese two rivers, according to Juul. Correlations between specific discharge rates from\nthose two rivers and the observed temporal changes in limnological parameters we\nobserved within the reservoir would be important factors in evaluating possible impacts\nof reservoir drawdown.\nThe relatively short duration of our study (March 1994 to October 1995) and the\nlong-term variability of major factors affecting water quality within Lower Granite\nReservoir make it difficult to elucidate possible relationships between the parameters we\nmonitored. In addition, since no drawdown occurred, there is no comparison to evaluate;\ntherefore no rigorous statistical assessments were prepared. We discuss below some of\nthe general limnological relationships important to the biota of Lower Granite Reservoir.\nThe results of our study and those of the previous pre-impoundment (1970-72)\nand post-impoundment (1975-77) studies were similar, although somewhat difficult to\ndirectly compare (USACE 1973, Funk et al. 1979). Before construction of Lower Granite\nDam was completed, the maximum surface-to-bottom difference in water temperature\namong the four lower Snake River reservoirs was 3.5°C (USACE 1973). Following\nimpoundment in 1977, the maximum surface-to-bottom difference in water temperature\nincreased to about 4.6°C. The maximum surface-to-bottom difference we observed\noccurred in July and August 1994 (about 3°C), but we typically measured temperature\nprofiles within our study areas to an 18-m depth, and the surface-to-bottom temperature\ndifference may have been greater in deeper areas of the reservoir.\nDissolved oxygen is released into the water by phytoplankton as a by-product of\nphotosynthesis. Saturation of dissolved oxygen at and near the water surface observed in\nAugust and September 1994 was possibly a result of increased phytoplankton\nproductivity (i.e., increased photosynthesis). As phytoplankton is consumed by\nzooplankton, the secondary producers, dissolved oxygen in the water decreases. This\nmay have in part contributed to the oxygen depletion observed near the bottom at the\nthree sampling areas during August and September 1994.\nWater temperature can affect algal growth (McKee and Wolf 1963,\nSchwoerbel 1987), and our sampling revealed correspondingly low concentrations of\nchlorophyll in areas where water temperature was lower than 10°C. Water temperature\nmay also have affected the observed seasonal changes in cladoceran abundance. Pennak\n39","(1989) observed higher cladoceran densities in the spring and summer when water\ntemperature ranged between 6 and 20°C. He also noted that a second seasonal peak in\ncladoceran abundance may occur in the fall before temperatures drop during winter; a\ntrend similar to the patterns observed in our study.\nOur observations of temporal and seasonal changes in nitrogen and phosphorus\nconcentrations were similar to those seen in pre-impoundment/post-impoundment studies.\nNitrogen and phosphorus concentrations declined during spring, were low during\nsummer, increased through fall, and remained high over winter (USACE 1973, Funk et\nal. 1979). Such seasonal changes were also observed for sulfate in pre-impoundment\nstudies and our study.\nNitrogen and phosphorus are utilized by phytoplankton for photosynthesis of\nchlorophyll (McKee and Wolf 1963, Round 1981, Sze 1986, Schwoerbel 1987).\nPhosphorus was observed to promote algal growth, especially for conversion of ADP to\nATP in photosynthesis, and this growth then causes the amount of available\northophosphate to decline (Schwoerbel 1987). Availability of nitrogen and phosphorus\nmay have limited chlorophyll production in our study areas. Cations and anions are also\nrequired for growth of phytoplankton (Welch 1952, Sze 1986, Schwoerbel 1987), but we\nsaw no evidence that they were limiting factors in phytoplankton production in our study\nareas.\nSilica concentrations greater than 0.5 mg/L are required for growth of diatoms\nwhich utilize silica as building material for cell walls (McKee and Wolf 1963,\nRound 1981, Schwoerbel 1987). Growth of diatoms is optimal when water temperature\nis between 15 and 30°C (McKee and Wolf 1963). Round (1981) reported that in\nfreshwater habitats, few organisms besides diatoms use silica, and changes in\nconcentrations of silica in the water generally are related to growth of diatoms. Silica\nconcentrations at our sampling areas were higher than 5 mg/L, and during some months\nwater temperatures were within the range for optimal diatom growth.\nThe diversity and abundance of freshwater ploimate rotifers (i.e., Brachionus,\nKeratella, Kellicottia) are affected by pH (Pennak 1989). Alkaline waters generally have\nmany species with few individuals, whereas acidic waters have few species with many\nindividuals. In our samples, we found 31 species of rotifer, the following 5 of which\nrepresented genera generally restricted to water with pH higher than 7.0: Asplanchna,\nMytilina, Brachionus, Filinia, and Notholca.\nZooplankters in general graze on phytoplankton for food, which in turn affect\nchlorophyll production and other chemical parameters in the water. A population growth\nof zooplankton could increase the consumption rate of phytoplankton; thus phytoplankton\npopulations and measured chlorophyll concentrations would decline.\n40","Factors affecting changes in the in zooplankton population include predator-prey\nrelationships, species competition, food availability, and physical and chemical\ncharacteristics of the water (Edmondson 1959, Gilbert 1980, Gliwicz and\nPijanowska 1989, Pennak 1989). For instance, after cladoceran densities of Daphnia and\nBosmina decline, the population of Ceriodaphnia, which was observed in our samples,\nmay increase (Gliwicz and Pijanowska 1989). In research on stomach contents of\noutmigrating subyearling and yearling chinook salmon (Oncorhynchus tshawytscha) in\nthe Columbia River system, including those in the lower Snake River, cladocerans\n(mostly Bosmina and Daphnia), and to a lesser extent copepods, constituted the diets of\nthe juvenile salmonids (Becker 1973, Craddock et al. 1976, Dauble et al. 1980, Kirn et\nal. 1986, Muir and Emmett 1988, Muir and Coley 1996). The feeding of juvenile\nsalmonids on cladocerans and copepods could also affect overall zooplankton species\ncomposition and numerical abundance in the reservoir.\nThe frequency of these natural but subtle periodicities in the food web were not\nnecessarily accurately reflected in our bimonthly/monthly sampling schedule. Had\nreservoir drawdown occurred and sampling proceeded into the drawdown period and\nthrough a post-drawdown recovery period, our sampling periodicity probably would have\nbeen adequate to describe the major limnological consequences of the drawdown event.\n41","CONCLUSIONS\nWater concentrations of physical and chemical parameters were similar between\n1)\nthe three sampling areas and between the water surface and the 15-m depth.\nGenerally, the water was well mixed with seasonal or temporal changes.\nThe three shallow-water areas sampled during 1994-95 had similar availability of\n2)\nnutrients. Availability of nitrogen and phosphorus may have limited chlorophyll\nproduction at times.\nZooplankton in the three shallow-water areas sampled during 1994-95 were\n3)\nnumerically dominated by rotifers. Cladocerans, copepods, and ostracods were\nalso present to a lesser extent. There were no strong temporal trends evident in\nzooplankton population densities during our sampling, though lowest densities\noccurred during the winter months.\nThere were only slight temporal changes in sediment characteristics, but there\n4)\nwere obvious differences in sediment composition among sampling areas and\nbetween depths within sampling areas. Sand and fines were more abundant than\ngravel at all three sampling areas.\nThe frequency of natural but subtle periodicities in the food web were not\n5)\naccurately reflected in our bimonthly/monthly sampling schedule.\n42","ACKNOWLEDGMENTS\nWe gratefully acknowledge the assistance of Dr. Stephen Juul and his staff at the\nWashington State University, Water Resource Center (WRC). Dr. Juul assisted us in the\nestablishment of experimental protocols and logistics necessary for transporting water\nsamples from the field to the Water Resource Center laboratory for timely processing.\nDuring the startup period of the study, Dr. Juul and his staff helped us verify proper\ncalibration of electronic equipment in the field and provided direct comparison of our\nnewly acquired irradiameter with their existing unit. Until our laboratory facilities were\ncompleted, all chlorophyll analyses were conducted at the WRC, and when we took over\nthe analyses, the WRC staff worked closely with us to develop laboratory techniques to\nprovide continuity in analysis. In addition, Dr. Juul gave freely of his time during often\nlengthy telephone conversations regarding the ongoing limnological investigations.\nMany individuals assisted in boat operations, data collection, data entry and\nverification, and data analysis, and many working on other projects made themselves\navailable for the 2 to 4 days every other week or at monthly intervals when we required\nassistance.

We used a 16-m-long by 38-mm-id hose to\nsample from the 0- to 15-m depth and a 7-m-long by 50-mm-id\nhose to sample from 0.5 m below the euphotic zone. Each hose\nhad a weight, a rope attached to the distal end, and a cap on the\nother end.\nTwo clean 19-L buckets.\n2.\nFour 500- to 1000-mL brown and opaque plastic bottles for each\n3.\ncomposite sample.\nOne 25-um plankton net with a sealed end for filtering water\n4.\nsamples.\nOne large cup for dipping subsamples from buckets and pouring\n5.\nthem into sample bottles.\nOne ice chest and ice necessary for keeping water samples cold and\n6.\nin the dark.\nProcedure: Water samples for analysis of chlorophyll a concentrations\nB.\nwere collected from generally the 18-m depth contour at each sampling\narea. Chlorophyll a concentrations were used as an index of\nphytoplankton biomass (APHA 1992). Composite samples were collected\nfrom the water surface to a depth of 15 m. In April 1995, we modified this\nprocedure to sample from 0.5 below the euphotic zone, which was\ndetermined with an irradiameter. In April, July, and October 1995, an\nadditional set of samples was collected from the water surface to the 15-m\ndepth. These additional samples were collected to compare chlorophyll\nconcentrations between fixed 0- to 15-m depth samples and variable\neuphotic zone plus 0.5-m depth samples.\n47","Each chlorophyll sample was obtained with a 38- or 50-mm-id\nhose, weighted and attached with a rope at the distal end, and deployed\nvertically to a specified sampling depth in the water column (Goldman and\nHorne 1983). The surface end of the deployed hose was capped and the\ndistal end was retrieved from the bottom using the attached rope (Goldman\nand Horne 1983). After retrieval, the composite sample in the hose was\nemptied into a 19-L bucket for mixing and subsampling. Two subsamples\nwere obtained from the bucket and poured into brown and opaque plastic\nbottles. Because a large portion of the phytoplankton often occurs in the\n< 25-um size fraction (Lieberman 1992), two additional subsamples were\nobtained after filtering the composite sample through a stoppered 25-um\nplankton net. Beginning in March 1995, we modified the procedure to\nobtain two independent composite samples from the reservoir: we took\none unfiltered subsample and one filtered subsample at each site. The four\nsubsamples were immediately stored in an ice chest to keep them cold and\ndark until transport to the laboratory for processing. From March to June\n1994, the chlorophyll samples were taken to the State of Washington\nWater Research Center, Washington State University, Pullman, WA (Dr.\nSteve Juul, point of contact) for analysis under contract; thereafter,\nsamples were transported to and analyzed at our laboratory. Upon arriving\nat our laboratory, the samples were put in the refrigerator overnight unless\nfiltration took place immediately. Samples were filtered within 3 days of\ncollection.\nII.\nFiltration\nA.\nEquipment\nSix 250-mL capacity Nalgene filter funnels for 47-mm diameter\n1.\nfilters.\nWhatman GF/C glass fiber filters (1.2 um pore size) with 47-mm\n2.\ndiameter.\nReservoir to support filter funnels and hold up to 6 L of filtrate.\n3.\nSix 500-mL graduated cylinders to measure water samples.\n4.\n5.\nTubing.

Filtration was\nconducted in subdued light (APHA 1992). Glass fiber filters were placed\nonto the filter funnel apparatus and dampened with distilled water from a\nwash bottle. Before adding water samples, suction was applied to the\ndampened filters with the vacuum pump to assure that the filters did not\nleak. For each subsample, the water in the sample bottle was thoroughly\nshaken to assure it was well mixed before measuring the water in a\ngraduated cylinder. Depending on turbidity, up to 1000 mL of the water\nsample were suction filtered with a vacuum pressure not exceeding 25 cm\nHg (Wetzel and Likens 1991). After filtration, the filter was transferred to\na numbered petrislide using forceps. Petrislides were wrapped in\naluminum foil and labeled, then stored in the freezer (< 32°C) prior to\nextraction. Labelling included reservoir, collection date(s), sample\nnumbers, and filtration date. The pH of several subsamples from each\nsampling trip was measured to ascertain that pH values were > 7. Because\nwe never measured pH <7 in the field or in the laboratory, we found it\nunnecessary to buffer water samples with saturated magnesium carbonate\nsolution (APHA 1992).\nIII.\nExtraction\nA.\nEquipment\n1.\nTissue grinder.\nA 30-mL capacity grinding tube (Thomas or Kontes) with a\na.\npestle.\nb.\nMotor for turning the pestle in the grinding tube.\nStand with clamp to hold motor and pestle.\nC.\nCentrifuge tubes with 15-mL capacity and caps.

The entire extraction procedure was conducted in\na fume hood. Two blank extracts were made for each set of samples for\nbaseline corrections of the spectrophotometer and for comparisons with\nthe samples. Using forceps, each slightly thawed sample filter was folded\ninto quarters (phytoplankton to the inside) and placed into the bottom of a\n30-mL grinding tube (Wetzel and Likens 1991).\nA total of 10 mL of 90% aqueous acetone was used in three\nseparate portions during this extraction procedure. First, 3.33 mL of 90%\naqueous acetone was added to the grinding tube, then the filter was ground\nfor 45 seconds with a pestle and motor (Wetzel and Likens 1991). The\n4\nWhile setting up the laboratory and developing the method for chlorophyll analysis,\nsamples on filters were frozen from 3 days to several months.\n50","resulting slurry was poured into a numbered 15-mL centrifuge tube and\ncapped to prevent evaporation of the acetone. Another 3.33 mL of 90%\naqueous acetone was added to the grinding tube in which the remaining\nslurry was ground for 15 seconds (Wetzel and Likens 1991). The slurry\nwas added to the numbered 15-mL centrifuge tube and recapped.\nA third 3.33-mL portion of 90% aqueous acetone was added to the\ngrinding tube for a final rinse with the pestle for approximately 5 seconds.\nThis rinse was poured into the numbered 15-mL centrifuge tube and\ncapped, making a total extract volume of 10 mL. Between samples, the\ngrinding tube was rinsed with 100% acetone using a wash bottle, and the\npestle was spun in it once more. The acetone rinse was then decanted into\na beaker for used acetone. Both the grinding tube and pestle were wiped\nclean with a laboratory tissue. Upon extraction of samples, the numbered\ncentrifuge tubes in test tube racks were covered with aluminum foil\nlabeled with reservoir, collection dates, sample numbers, and extraction\ndates, and stored in the refrigerator for 24 hours prior to\nspectrophotometric analysis (APHA 1992).\nSpectrophotometric Analysis\nIV.\nA.\nEquipment\nA spectrophotometer with wavelengths set at 630.0, 647.0, 664.0,\n1.\n750.0, and 665.0 nm. We used a Shimadzu UV-160U\nspectrophotometer.\nSpectrophotometric cuvettes. Eight cuvettes were used for our\n2.\nanalyses.

The tubes were then spun at\nabout 2000 rpm in a centrifuge for 2 minutes (Wetzel and Likens 1991).\nEach capped tube was taken out to remove debris from the inside of the\ntube by rolling. The tubes were then spun for an additional 18 minutes.\n(Wetzel and Likens 1991).\nThe spectrophotometer was set to use five different wavelengths:\n630.0 nm for chlorophyll c, 647.0 nm for chlorophyll b, 664.0 nm for\nchlorophyll a before acidification, 750.0 nm for turbidity, and 665.0 nm\nfor chlorophyll a after acidification (APHA 1992). Each cuvette was\nrinsed with 100% acetone prior to analysis. One cuvette containing a\nblank extract was put in the reference cell holder, and the second cuvette\ncontaining the other blank extract was put in the sample cell holder. The\nbaseline correction was run on the spectrophotometer according to the\nspectrophotometer's manual, then with the two cuvettes still in the cell\nholders, a photometric reading was obtained of the blank extract. The\ncuvettes with the blank extracts were switched before a second\nphotometric reading was obtained.\nPrior to mid-June 1995, we used cuvettes with a 1-cm cell path\nlength to analyze samples. In mid-June 1995, we began using cuvettes\nwith a 5-cm cell path length which allowed the 664- and 665-nm\nwavelength readings to be between 0.1 and 1.0 for better precision of the\nwavelength absorbance of sample extracts.\nSpectrophotometric readings of each sample extract before and\nafter acidification was obtained. One cuvette containing a blank extract\nwas placed in the reference cell for comparison with the extract of the\nchlorophyll samples. For each sample, extract was transferred to a clean\ncuvette using a disposable pipet as described by APHA (1992). Volume\nof extract necessary for analysis was 3 mL for a 1-cm cell path length and\n6 mL for 5-cm cell path length (APHA 1992). Prior to analysis, the\ncuvette containing the extract was wiped with lens paper. With the cuvette\nplaced in the sample cell holder of the spectrophotometer, a\nbefore-acidification reading was obtained of the extract. After this\nreading, a repipet with a disposable tip was used to add to the extract 0.1\nmL of 0.1 mol/L hydrochloric acid for a 1-cm cell path length, or 0.2 mL\nof the same acid for a 5-cm cell path length (APHA 1992). The cuvette\n52","was gently agitated and placed back in the spectrophotometer. Ninety\nseconds after acidification, a second reading was obtained of the acidified\nextract. The acidification procedure determines the deterioration ratio of\nchlorophyll a to pheophytin a, which should be near or at 1.7 (APHA\n1992). Between samples, the cuvette was rinsed with 100% acetone.\nV.\nData processing\nThe spectrophotometer we used printed photometric readings of the\nA.\ndifferent wavelengths. Appropriate numbers from these readings were\nentered into a relational database (Microsoft Access version 2.0).\nCalculations of monochromatic chlorophyll a (pheophytin-corrected),\nB.\ntrichromatic chlorophyll a, b, and c, pheophytin a, and deterioration ratio\nwere derived from the formulas given by APHA (1992). A computer\nprogram was written in our database to perform these calculations, which\nwere also verified manually.\nData analyses excluded chlorophyll concentrations having a deterioration\nC.\nratio outside the range of 1.0 to 1.7.\n53","","Appendix B.
