It is also the first dam downstream from the confluence\nof the Columbia and Snake Rivers, influencing anadromous fish\nmigrations from both river systems. After the completion of\nMcNary Dam in 1954, Schoeneman et al. (1961) estimated that\nyearling chinook salmon (Oncorhynchus tshawytscha) passing\nthrough turbines at the dam incurred 11% mortality.\nA juvenile fish bypass system, installed at McNary Dam in\n1981, includes a collection facility for handling salmonids in\npreparation for transportion by barge or truck to a release site\nbelow Bonneville Dam. The standard-length submersible traveling\nscreens (STS), , designed and installed to divert juvenile\nsalmonids away from the turbine intakes and guide them into\ngatewells for collection, are an essential component of the\nbypass system.\nInitial research by the National Marine Fisheries Service\n(NMFS) indicated that although the fish guidance efficiency (FGE)\nachieved with STSs for yearling chinook salmon and steelhead\n(O. mykiss) was acceptable (>70%), generally less than 50% of the\nsubyearling chinook salmon were guided (Krcma et al. 1983; Swan\nand Norman 1987; Brege et al. 1988) . In 1984, the FGE achieved\nwith STSs for subyearling chinook was 33-46% (Krcma 1985)\n.\nSeveral investigators have noted a general inverse\nrelationship between FGE for subyearling chinook and","2\nsurface-water temperature, possibly indicating an avoidance\nbehavior (e.g., Krcma et al. 1983; Krcma et al. 1985; Wagner\n1989; Gessel et al. 1991) . Additional testing at McNary Dam\nsuggested that guidance could be improved using a device which\nextended deeper into the water column (Swan and Norman 1987) .\nDuring spring and summer 1991, NMFS began testing an\nextended-length submersible traveling screen and an\nextended-length submersible bar screen; each was approximately\n12.1 m (40 ft) long, or twice the length of the STS. Both\nextended-length screens increased FGE to about 80% for yearling\nchinook salmon and to well over 50% for subyearling chinook\nsalmon, with no significant difference between devices (Brege\net al. 1992) However, the extended-length bar screen caused\nless descaling of guided fish than the extended-length traveling\nscreen. Therefore, the extended-length bar screen received\nfurther FGE evaluation at McNary Dam in 1992 and the extended-\nlength traveling screen was used only for descaling tests while a\nredesigned, more streamlined extended-length traveling screen was\nbeing developed for prototype testing in 1993.\nThere is conflicting evidence concerning the relationship\nbetween physiological development and FGE. Data acquired at\nLower Granite and Little Goose Dams from 1985 to 1989 suggested\nthat fully smolted yearling chinook salmon were more susceptible\nto guidance by traveling screens than fish at intermediate stages\nof smoltification (Swan et al. 1987; Giorgi et al. 1988; Muir\net al. 1988; Muir et al. 1990). However, research at Bonneville\nDam in 1988 (Muir et al. 1989) and at McNary Dam in 1991 (Brege\net al. 1992) found no significant relationship between","3\nphysiological development, as measured by gill Na a+-K+ ATPase\nlevels, and FGE.\nIn 1992, NMFS, under contract to COE, tested the comparative\nabilities of the extended-length bar screen and STS to guide\njuvenile salmonids from turbine intakes, as well as their\nrelative effects on fish condition. Chinook salmon smolt\ndevelopment was monitored periodically in an attempt to correlate\nFGE to degree of smoltification.\nSpecific objectives in 1992 were:\n1) Compare the fish guidance efficiency of the extended-length\nbar screen and the STS (control) for juvenile salmonids,\nparticularly yearling and subyearling chinook salmon during\nthe spring and summer outmigrations.\n2) Evaluate the effect of the extended-leng\\.h bar screen on\njuvenile salmonid descaling and compare to descaling with the\nSTS (control) .\n3) Measure levels of smoltification in yearling and subyearling\nchinook salmon collected in gatewells and fyke nets during FGE\ntests conducted in the early, middle, and late segments of the\nspring and summer outmigrations.\nIn addition to the NMFS research, personnel from the COE's\nWaterways Experiment Station (WES) used underwater video imaging\ntechniques to provide information concerning fish behavior near\nthe surface of the guiding devices and the vertical barrier\nscreen. Also, as part of a cooperative effort, bacterial kidney\ndisease (BKD) analysis was performed by U.S. Fish and Wildlife\nService (USFWS) personnel on fish collected for smoltification","4\nmeasurements. Results of these two studies will be reported\nelsewhere.\nOBJECTIVE 1 : FISH GUIDANCE EFFICIENCY OF THE EXTENDED-LENGTH\nBAR SCREEN AND THE STANDARD-LENGTH SUBMERSIBLE TRAVELING SCREEN\nApproach\nMethods for determining FGE were similar to those used by\nBrege et al. (1992) . Extended-length bar screens and fyke-net\nframes were placed in the B slots of Turbine Units 5 and 6\n(Fig. 1) . The half nets used in the upper two rows in 1991 were\nreplaced with standard-size fyke nets in this study, since half\nnets provided no additional statistical benefit. Therefore, the\nfyke-net array used in 1992 consisted of three columns of seven\nnets or a complete complement of 21 nets per fyke-net frame\n(Fig. 1) . Fyke nets were placed in the downstream (operating\ngate) slot because the size of the extended-length screen\nprecluded direct attachment to the screen as done with the STS.\nEither extended-length bar screens or extended-length traveling\nscreens were placed in the A and C slots of the test units to\nmaintain uniform flows across the turbine intake. Extended-\nlength traveling screens were modified by perforated plate\nporosity changes to reduce fish descaling. Initial screen\nconditions in test and control units were:","5\nMcNary Dam cross section\n1992 Fyke-net layout\nExtended-length\nNorth Middle South\nRow\nsubmersible\nGatewell\n1\nbar screen\n(bulkhead slot)\n2\nGate slot\n3\nJuvenile fish\n4\nbypass flume\n5\nOperating gate\n(raised position)\n6\n7\nVertical barrier screen\nStandard\nNorth Middle South\nRow\nlength\n1\nsubmersible\ntraveling\n2\nscreen\n3\n20\n4\nExtended-length\nsubmersible\n5\nFyke\nbar screen\nnets\n6\n7\n080\nFyke net with cod end\nFyke net without cod end\nFigure 1. . -- -Cross section of turbine unit at McNary Dam with extended-length\nsubmersible bar screen and fyke nets in place.","6\nPerforated\nTurbine\nScreen\nplate\nunit/slot\ntype\nporosity (%)\n5A\nExtended-length STS\n25\n5B\nExtended-length bar screen\n33\n5C\nExtended-length STS\n34\n6A\nExtended-length bar screen\n30\n6B\nExtended-length bar screen\n37\n6C\nExtended-length STS\n34\n7B (Control)\nSTS\n48\nExtended-length screen slots in Turbine Units 5 and 6, and\nthe control slot (7B) contained modified balanced-flow vertical\nbarrier screens that separated the bulkhead slot (gatewell) from\nthe operating gate slot and served to confine guided fish to the\ngatewell (Fig. 1) . The difference between the vertical barrier\nscreens used with the extended-length and standard-length\nguidance screens was the addition of a solid plate panel on the\nbottom section of the vertical barrier screen used with the\nextended-length screen (Fig. 2) . This panel change was an\nattempt to improve conditions on immediate entry into the\ngatewell where flows increased due to the raised operating gate\nand the additional water column intercepted by extended-length\nscreens.\nThough test conditions varied for the extended-length\nscreens in Slots 5B and 6B with regard to screen elevation,\nperforated plate porosity, and operating gate position, the STS\nin Slot 7B (control) was maintained at standard elevation with a\n48% perforated plate porosity and with no operating gate (i.e., ,\nan operating gate that was fully raised or removed) for all","7\n2a.\n2b.\nFigure 2.\n.

Shaded\nsections represent solid plate; open areas are\nmonofilament mesh with perforated plate backing.\nAll slots in test Units 5 and 6 contained the\nconfiguration in 2a. Slot 7B (control) had the\narrangement shown in 2b.","8\ntests. Screen angle was held constant at 55° for all screens\nthroughout the 1992 field season.\nFlows into test- and control-turbine intakes were maintained\nat 16,000 cfs for FGE studies during the yearling chinook salmon\noutmigration and reduced to 15,000 cfs for the subyearling run.\nThis corresponded to a screen-approach velocity of about 2.5 fps\nand to turbine-unit loads of approximately 80 and 75 MW\n(dependent on forebay elevation) for the spring and summer runs,\nrespectively.\nGatewell dipbasket catches provided the number of guided\nfish while the fyke-net catch yielded the number of unguided\nfish. Cod ends were placed on all fyke nets used with the\nextended-length bar screens. With the STS (control), however,\ncod ends were used only on the center column of fyke nets\n(Fig. 1) . This was done with the STS to minimize fish\nmortalities and because previous statistical analyses of a\nsimilar configuration indicated that multiplying the\ncenter-column catch by 3 would provide a reasonable approximation\nof the total fyke-net catch (Gessel et al. 1986) Fish guidance\nefficiency for the extended-length bar screens was calculated as\nthe number of guided fish divided by the total number of fish (by\nspecies) entering the turbine intake:\nFGE GW+FN X 100%\n=\nwhere GW = gatewell catch\nFN = fyke-net catch.","9\nTesting typically began at 2000 h and terminated when enough\nfish (>200) of the target species had been collected. Test dates\nand conditions for individual test series are listed in Table 1.\nAll tests were carried out simultaneously for a given date in\ntest slots 5B, 6B, and 7B. To accommodate the randomized block\ndesign and provide adequate statistical resolution, extended-\nlength bar screen tests were conducted daily, while STS tests\nwere conducted every second test day during the spring\noutmigration. Slot 5B was not available for FGE tests from 6 to\n16 July. Also, due to procedure problems, data obtained for the\nnight of 6 July were omitted from analyses. Following 6 July,\nthe test design was modified to a randomized block analysis of\nvariance, initially to a 4-day block design, utilizing Slot 6B\nonly, and later to a 2-day block design, when Slot 5B became\navailable. The STS in the control slot (7B) was tested daily\nduring this summer period.\nDipbasket efficiency testing was conducted as in past FGE\nstudies (Krcma et al. 1985) . Freeze-branded yearling chinook\nsalmon and steelhead, obtained from the juvenile fish-collection\nfacility at McNary Dam, were released into the gatewell of the\ntest unit prior to the start of the FGE test, and removed after\nthe test along with the gatewell catch.\nResults and Discussion\nA dipbasket efficiency test was conducted during the FGE\ntest in Slot 6B on 29 May. Test results indicated a dipbasket\nefficiency of 96.9% for yearling chinook salmon and 94.9% for\nsteelhead.","10\nTable 1. --Test schedule for the 1992 field season at McNary Dam.\nScreen angle was maintained at 55° for all tests, with\nmodified balanced flow vertical barrier screens in all test\nand control slots.\nOperating\nPerforated\nTest\nTest\nTest\nGuidance\nUnit\nFlow\ngate\nplate\nScreen\nseries\ndates\ntype\ndevice\nslot\n(kcfs)\nposition\nporosity\nelevation\n(%)\n1\n27 - 28 April\nFGE*\nESBSb\n5B\n16\nNOG\n33\nStd / low 60 cm®\nStd/low 90 cm2\nFGE\nESBS\n6B\n16\nNOG\n37\nSTS\nFGE/Des\n7B\n16\nNOG\n48\nStd\n2\n29 - 30 April\nFGE\nESBS\n5B\n16\nNOG\n33\nStd/low 60 cm\n4 - 5 May\nFGE\nESBS\n6B\n16\nNOG\n30\nStd/low 60 cm\nFGE/Des\nSTS\n7B\n16\nNOG\n48\nStd\nPROG1\n3\n6 -\n8 May\nFGE\nESBS\n5B\n16\n33\nStd/low 60 cm\nFGE\nESBS\n6B\n16\nPROG\n30\nStd\nStd\nFGE/Des\nSTS\n7B\n16\nNOG\n48\nESTS\n4\n11 - 15 May\nDes\n5A\n16/12\nSOG\n25\nStd\nDes\nESBS\n5B\n16/12\nSOG\n26\nStd\nDes\nESBS\n6A\n16/12\nNOG\n30\nStd\nDes\nESBS\n6B\n16/12\nSOG\n30\nStd\nDes\nSTS\n7B\n16/12\nNOG\n48\nStd\n5\n18 - 21 May\nDes\nESTS\n5A\n16\nSOG\n25\nStd\nFGE\nStd\nESBS\n5B\n16\nPROG\n26\nDes\nESTS\n5C\n16\nNOG\n34\nStd\nDes\nESBS\n6A\n16\nNOG\n30\nStd\nFGE\nESBS\n6B\n16\nPROG\n30\nStd\nFGE/Des\nSTS\n7B\n16\nNOG\n48\nStd\n6\n26 - 29 May\nDes\nESTS\n5A\n16\nSOG\n25\nStd\nFGE\nESBS\n5B\n16\nNOG\n26\nStd\nDes\nESTS\n5C\n16\nNOG\n34\nStd\nDes\nESBS\n6A\n16\nNOG\n30\nStd\nFGE\nESBS\n6B\n16\nPROG\n30\nStd\nFGE/Des\nSTS\n7B\n16\nNOG\n48\nStd\n7\n22 - 29 June\nFGE\nESBS\n5B\n15\nNOG\n33\nStd\nFGE\nESBS\n6B\n15\nNOG\n30\nStd\nFGE\nSTS\n7B.\n15\nNOG\n48\nStd\n8\n6 - 11 July\nFGE/Des\nESBS\n5B\n15\nNOG/PROG\n30\nLow 60 cm\n13 - 18 July\n15\nFGE\nESBS\n6B\nNOG/PROG\n30\nStd/low 60 cm\n20 - 24 July\nFGE\nSTS\n7B\n15\nNOG\n48\nStd\nFish guidance efficiency test (includes descaling)\n9 Descaling test, separate from FGE tests.\nExtended-length submersible bar screen.\nStandard-length submersible traveling screen.\n1\nNo operating gate (fully raised or removed).\nPartially raised operating gate (raised 2.4 m)\n1\nExtended-length submersible traveling screen.\nStandard screen elevation.\nScreen lowered 60 cm below standard elevation.\nStored operating gate (standard position)\nScreen lowered 90 cm below standard elevation.","11\nYearling Fish\nFGE tests for yearling chinook salmon were conducted in\n5 series from 27 April through 29 May (Table 1,\nTest Series 1-3,5,6). Results for individual test nights are\npresented in Appendix Table 1. Fish guidance efficiency averaged\n80% (SE = 1.0) for the combined extended-length screens compared\nto 61% (SE = 5.9) for the STS during the yearling chinook salmon\nspring outmigration.\nMean FGE values with extended-length bar screens for\nyearling chinook salmon were 82% (SE = 1.1) on the first night of\ntesting and 75% (SE = 9.2) on the second, with no operating gate\nin the test units and 33 and 37% perforated plate porosities,\nrespectively. By comparison, FGE for one test with the STS\n(control) during this period was 53% (Fig. 3, Test Series 1) .\nHowever, mean descaling for the extended-length bar screens (28.9\nand 23.4% for Slots 5B and 6B, respectively, 26.2% combined) was\nover three times higher than descaling in the control unit\n(8.6%). Additionally, the fyke-net catch distribution with the\nextended-length bar screen in the 90-cm (36-in) lowered position\nindicated that a high percentage (20%) of fish passed through a\ngap between the turbine intake ceiling and the extended-length\nbar screen, reducing FGE (Figs . 3 and 4, Slot 6B, Test Series 1)\n.\nA direct measure of loss through this gap was not possible due to\nthe placement of the fyke-net frame in the downstream (operating\ngate) slot, which prevented the use of a gap net. As a\nconsequence of unacceptable descaling and the apparent gap loss,\nthe 90-cm lowered screen condition was omitted from further","12\nFGE (%)\n100\n5B, ESBS\n6B, ESBS\n7B, STS\n80\n60\n40\n20\n0\n1\n2\n3\n5\n6\nTest series\nFigure 3.

One\nmajor area of concern was the high flow (near 600 cfs) into the\ngatewell slot using the extended-length screens with no operating\ngate. It was calculated that raising the operating gate 2.4 m\nabove the stored operating gate position would restrict flows\ninto the gatewell slot to about 450 cfs. This flow rate would be\nsimilar to flows achieved with the STS using no operating gate\nwhich produced relatively low descaling.\nA three-night block of tests was carried out to investigate\nthe possibility that a partially raised operating gate would\ncontrol flows into the gatewell. It was hoped the partially\nraised gate would enable fish to avoid striking either the\nextended-length bar screen or the vertical barrier screen, and","15\nthereby lower descaling. With the operating gate raised 2.4 m\nabove the normal stored position, FGE for the extended-length bar\nscreen averaged 81% with both the 33 and 30% perforated plate\nporosities, respectively (SE = 1.7 and 3.6), and descaling was\nreduced to respective means of 18.1 and 12.4%. The STS had a\nmean FGE of 71% (Fig. 3, Test Series 3) and mean descaling of\n8.4%. The 60-cm lowered-elevation setting with the extended-\nlength bar screen was eliminated as a test condition following\nTest Series 3 because it apparently neither increased FGE nor\ndecreased descaling.\nFor the final two spring FGE test series, the 33% perforated\nplate porosity with the extended-length bar screen in Slot 5B was\nchanged to 26%. This was done to examine the hypothesis that a\nperforated plate porosity lower than 30% would further decrease\ndescaling while maintaining acceptable FGE. The mean FGE values\nin Slot 5B were 76 (SE = 1.7) and 75% (SE = 1.7) with a partially\nraised operating gate (Test Series 5) and no operating gate (Test\nSeries 6) respectively (Fig. 3) For the extended-length bar\nscreen with a partially raised operating gate and 30% perforated\nplate porosity in Slot 6B, mean FGE was 82 (SE = 1.3) and 78%\n(SE = 4.0) for Series 5 and 6. Fish guidance efficiency for the\nSTS averaged 78 (SE = 13.0) and 64% (SE = 3.1) for these series,\nrespectively.\nThere was a marked difference in fyke-net catch distribution\nbetween screen types (standard vs. extended-length) and between\nseries for the extended-length screens (Fig. 4). With the STS in\nSlot 7B, captures tended to concentrate at Net Levels 3 and 4,","16\nwhile the net level of captures with the extended-length bar\nscreens varied by series. When screens were lowered in the first\nthree series, catches were bimodal, with high numbers in Net\nLevels 2 and 5. As mentioned above, this suggested that a high\nproportion of fish were shunted over the top of the screen\n(through the gap) and into the fyke nets (at Net Level 2) rather\nthan deflected up into the gatewell. With the extended-length\nbar screen in Slot 6B lowered 90 cm on the first test night, the\nfirst three net levels accounted for 74% of the fyke-net\ncaptures. When the extended-length screens were set at standard\nelevation during the last two FGE series, Net Level 5 contained\nthe highest mean percentage of yearling chinook salmon (29.0% for\nSlot 5B and 34.2% for Slot 6B). Net Levels 3 and 4 accounted for\n72.6% of the total fyke-net catch in Slot 7B for the same two\nseries.\nSteelhead, coho (O. kisutch), and sockeye salmon (O. nerka)\nwere captured incidentally during FGE tests. Fish guidance\nefficiency values over the entire study period for each of the\nscreens and for each test are listed by species in Appendix\nTable 1.\nSubyearling Fish\nFish guidance efficiency testing with subyearling chinook\nsalmon began 22 June and ran through 24 July, comprising two\nseries (Table 1, Test Series 7 and 8) .\nDue to unacceptable performance in the spring test, the 26%\nperforated plate porosity on the extended-length bar screen in\nSlot 5B was changed to 33% for the first series (Series 7), while","17\nthe extended-length bar screen in Slot 6B retained the 30%\nperforated plate porosity. Also, based on 1991 test results,\nwhich indicated that increased flows into the gatewell improved\nguidance with little increased descaling for subyearling chinook\n(Brege et al. 1992), operating gates were removed from the\nextended-length screen test slots. With no operating gates in\nSlots 5B and 6B, FGE averaged 68 and 66%, respectively. The\ndifference was not significant (t = 1.33, df = 7, P = 0.2252) .\nThe second subyearling chinook series (Series 8) began as a\nsingle turbine unit 4-day block in Slot 6B, since Slot 5B was\ndedicated to WES investigations during this period. Combinations\nof screen elevation (standard vs. 60-cm lowered) and operating\ngate position (no operating gate vs. partially raised operating\ngate) were tested with the 30% perforated plate porosity. When\nSlot 5B became available again on 17 July, perforated plate\nporosity was changed to 30% and the test design was changed to a\ntwo-unit, 2-day block design with screens at lowered elevation in\nSlot 5B and standard elevation in 6B.\nSince the actual difference between FGE values for\nextended-length screens and those of standard-length screens\ncould be concealed by natural fluctuations in FGE values, the\nbeneficial effects of a given set of extended-length screen test\nconditions could be masked. To overcome this problem, means were\nadjusted by subtracting FGE values for the control condition (STS\nin 7B) from corresponding daily values for the extended-length\nscreens. During these test series, differences in FGE means for\nextended-length screens with subyearling chinook salmon were","18\nsimilar for both unadjusted and adjusted data. With screens at\nstandard elevation, unadjusted mean FGE values were 43 and 48%\nusing a partially raised operating gate and no operating gate,\nrespectively. Unadjusted means for screens at the lowered\nelevation were 45% with a partially raised operating gate and 47%\nwith no operating gate. None of the combinations of screen\nelevation and operating gate setting were significantly different\nfor either the unadjusted or adjusted data (F = 1.09, df = 1,14,\nP = 0.6822) .\nOver the course of the subyearling chinook salmon\noutmigration, FGE for the extended-length bar screen in Slot 6B\nwith a 30% perforated plate porosity averaged 53% with various\nscreen and gate settings. Mean FGE values for Slot 6B and the\ncontrol (STS in Slot 7B) were 50 and 30%, respectively, for those\ndays when the units were paired for testing purposes. This\nsignificant difference (t = 8.87, df = 19, P < 0.0001) clearly\nindicated the FGE benefits provided by the extended-length bar\nscreen for subyearling chinook salmon.\nOBJECTIVE 2: EFFECT OF THE EXTENDED-LENGTH BAR SCREEN\nON FISH CONDITION\nApproach\nFish condition was evaluated using standard criteria\ndeveloped by the Fish Transportation Oversight Team and was\ndefined as the number of descaled guided fish divided by the\ntotal number of guided fish recovered by species from the\ngatewell. All juvenile salmonids recovered from the gatewells\nwere examined for descaling during each of the FGE and descaling","19\ntests. The descaling test design followed that used for FGE\ntests, except that:\n1) Descaling was tested daily for the STS.\n2) From 10 May to the end of the yearling chinook salmon\noutmigration, additional testing was carried out on three\nscreens not included in the FGE tests (in Slots 5A, 5C,\nand 6A). This allowed monitoring of the effects of\nextended-length traveling screens in Slots 5A and 5C and\nprovided support for the WES effort in Slot 6A.\n3) A 1-week block of tests was added (Series 4) during\nwhich no FGE testing was done, to compare the effects of\nturbine intake flow variation on descaling. Stored\noperating gates were used in all units for this series\nsince this condition reduced flows into the gatewell and\nminimized descaling.\nDifferences between conditions were tested using two-sample\nand paired t-tests, two-factor analysis of variance, and\nrandomized block analysis of variance. Fisher's protected least\nsignificant difference (LSD) procedure was used to detect\ndifferences between treatments within blocks.\nResults and Discussion\nMean descaling results for yearling and subyearling chinook\nsalmon and steelhead are listed in Table 2 by series test date.\nAppendix Table 2 contains complete descaling data for all species\nby turbine unit and test date.","20\nTable 2. -Mean percent descaling of yearling and subyearling chinook\nsalmon and steelhead during FGE testing at McNary Dam, 1992.\nYearling\nSubyearling\nOperating\nchinook\nchinook\nGuidance\nsalmon\nSteelhead\nsalmon\nTest\nTest\nTest\ngate\nseries\ndates\nunit\ndevice\nposition\nMean\nSE\nMean\nSE\nMean\nSE\nNOGb\n1.5\n1\n27 - 28 April\n5B\nESBSa\n28.9\n19.7\n5.4\n6B\nESBS\nNOG\n23.4\n6.0\n17.8\n11\n6.7\n7B\nSTS\nNOG\n8.6\n21.6\n4.6\n10.2\n3.1\n2\n29 - 30 April\n5B\nESBS\nNOG\n19.3\n2.3\n7.1\n2.6\n4 - 5 May\n6B\nESBS\nNOG\n7B\n9.2\n0.7\n5.7\n3.9\nSTS\nNOG\n1.9\n3\n6 8 May\n5B\nESBS\nPROG®\n18.1\n3.3\n11.1\n6B\n0.8\n5.4\n0.9\nESBS\nPROG\n12.4\n7B\nSTS\nNOG\n8.9\n2.6\n4.7\n4.7\nESTS\n4\n11 - 15 May\n5A\nSOG\n16.2\n1.9\n7.1\n2.0\n(12 kcfs)\nESBS\n5B\n18.1\n2.6\n5.0\n2.6\nSOG\n6A\nESBS\n5.0\nNOG\n18.0\n5.0\n6B\nESBS\nSOG\n19.9\n6.7\n10.8\n7B\nSTS\nNOG\n10.9\n4.4\n6.8\n1.7\n4\n11 - 15 May\n5A\nESTS\nSOG\n15.1\n2.0\n8.9\n2.0\n(16 kcfs)\n5B\n17.3\n1.8\n5.7\n1.2\nESBS\nSOG\n6A\nESBS\nNOG\n10.7\n8.9\n6B\nESBS\nSOG\n16.1\n1.4\n5.6\n0.8\n7B\nSTS\nNOG\n8.8\n0.9\n5.9\n1.7\n5\n18 - 21 May\n5A\nESTS\nSOG\n13.9\n2.2\n9.7\n1.8\n5B\n14.3\n11.0\n1.9\nESBS\nPROG\n2.0\n5C\nESTS\nNOG\n11.0\n0.6\n12.7\n2.1\n6A\nESBS\nNOG\n9.0\n1.3\n11.0\n2.6\n6B\nESBS\nPROG\n9.9\n1.1\n9.3\n0.3\n7B\nSTS\nNOG\n9.3\n2.1\n9.6\n1.9\n6\n26 - 29 May\n5A\nESTS\nSOG\n21.3\n2.1\n13.9\n2.9\n5B\n24.7\nESBS\nPROG\n2.0\n17.8\n3.6\n5C\nESTS\nNOG\n25.3\n3.1\n8.4\n3.4\n6A\nESBS\nNOG\n17.6\n2.0\n12.0\n2.0\n6B\nESBS\nPROG\n16.0\n1.6\n15.1\n4.8\n7B\n1.7\n16.4\n2.1\nSTS\nNOG\n13.8\n7\n22 - 29 June\n5B\nESBS¹\nNOG\n8.0\n1.7\n6B\nESBS\nNOG\n4.5\n1.2\n7B\nSTS\nNOG\n6.3\n1.1\nESBS\n8\n6 - 11 July\n5B\nNOG/PROG\n12.3\n1.4\n13 - 18 July\n6B\nESBS\nNOG/PROG\n9.0\n2.0\n21 - 24 July\n7B\nSTS\nNOG\n2.9\n0.5\nf\nExtended-length submersible traveling screen.\na\nExtended-length submersible bar screen.\nNo operating gate (fully raised or removed)\ng\nStored operating gate (standard position)\nh Perforated plate porosity changed to 26%.\nc\nStandard-length submersible traveling screen.\n1\nd\nPerforated plate porosity changed to 30%\nPerforated plate porosity changed to 33%\nPartially raised operating gate (2.4 m raised)","21\nYearling Fish\nDescaling test analyses, results, and conditions for the\nvarious treatments are presented in Appendix Table 3.\nDescaling was the major consideration driving test design\nduring the spring outmigration in 1992. Various combinations of\noperating gate position, screen elevation, and perforated plate\nporosity were tested in an attempt to bring extended-length bar\nscreen descaling more in line with STS descaling (Fig. 5) . This\nresulted in a test design with few trials in some series, which\nlimited statistical resolution.\nInvestigation of the effect of lowering the extended-length\nscreen below standard elevation as a possible strategy for\nreducing descaling was abandoned after the first 2 weeks.\nHowever, a two-sample t-test revealed no difference in mean\ndescaling between the lowered and standard screen elevations for\nthe limited number of tests conducted in Slot 5B with a 33%\nperforated plate porosity (t = 2.02, df = 7, P = 0.08) .\nSimilarly, there was no difference between either of the\nextended-length screens with 33 and 30% perforated plate porosity\nand no operating gate when the screen elevations were randomly\nalternated between lowered and standard elevations (F = 3.11,\ndf = 2, 5, P = 0.13) However, when the same perforated plate\nporosity and screen elevation parameters were compared using a\npartially raised operating gate during the third test series, a\ndifference was found between the 33% perforated plate porosity\nwith extended-length bar screen in Slot 5B and both the 30%\nperforated plate porosity with extended-length bar screen in 6B","22\nPercent descaled\n30\n5B, ESBS\n6B, ESBS\n7B, STS\n25\n20\n15\n10\n5\no\n1\n2\n3\n4\n4\n5\n6\n-\n(12 kcts)\n(16 kcts)\nTest series\nFigure 5. -Mean descaling values for yearling chinook salmon\nobtained during fish guidance efficiency and\ndescaling tests with extended-length submersible\nbar screens (ESBS) and standard-length\nsubmersible traveling screens (STS) at McNary\nDam, 1992.

Each\nnight, flows of 12 and 16 kcfs were tested in each of the three\nturbine units. A two-factor analysis of variance revealed no\nsignificant differences in yearling chinook salmon mean descaling\nfor this test series comparing either flow (F = 0.63, df = 1,20,\nP = 0.4) or flow combined with screen effects (F = 0.10,\ndf = 5,15, P = 0.96). However, yearling chinook salmon descaling\nvalues were significantly lower in Slot 7B (control) than in the\nextended-length screen Slots 5B and 6B when only screen effects\nwere considered (F = 3.18, df = 3,20, P = 0.05)\nDescaling tests were conducted in Slots 5A, 5C, and 6A in\naddition to scheduled FGE testing in Slots 5B, 6B, and 7B during\nTest Series 5 (18-21 May) and 6 (26-29 May) (Table 2) There\nwere no significant differences in mean descaling values for\nyearling chinook salmon among any of the six slots tested during\nSeries 5 (F = 2.12, df = 5,15, P = 0.12) .\nSignificant differences in mean descaling values were found\namong the six slots for Test Series 6 (F = 4.30, df = 5,15, P =\n0.01). Analysis of data for Test Series 6 by Fisher's LSD","24\nprocedure revealed that mean descaling for Slot 7B (control) was\nsignificantly lower than mean descaling for any slots in Unit 5,\nand Slots 6A and 6B had significantly lower mean descaling than\nSlots 5B and 5C. However, for Test Series 6 there were no\nsignificant differences in mean descaling among slots within\nindividual units, among Slots 6A, 6B, and 7B, or among Slots 5A,\n6A, and 6B for Test Series 6.\nof all the configurations examined, the extended-length bar\nscreen in Slot 6B at standard elevation, with 30% perforated\nplate porosity, and with a 2.4-m partially raised operating gate,\nappeared to be the extended-length bar screen configuration which\ncaused the least descaling. A paired t-test between all\noccurrences of this combination of conditions for the extended-\nlength bar screen in 6B and the STS in 7B (control) revealed no\nsignificant difference (t = 1.96, df = 10, P = 0.08) in yearling\nchinook salmon descaling.\nSubyearling Fish\nDescaling tests for subyearling chinook salmon were\nconducted with FGE testing during the outmigration in June and\nJuly, and resulted in two complete series (Test Series 7 and 8,\nTable 2) .\nFor the first summer series, Slot 6B retained the 30%\nperforated plate porosity. The perforated plate porosity on the\nextended-length bar screen in Slot 5B was changed from 26 to 33%\nbecause of the poor performance at 26%. Since earlier testing\nhad indicated that subyearling chinook salmon were affected less\nthan yearling fish by increased flows into the gatewell,","25\noperating gates were not used in either test or control slots\nduring the first subyearling test (Test Series 7) Descaling\naveraged 8.0, 4.5, and 6.3 in Slots 5B, 6B, and 7B, respectively.\nThe differences were not significant when analyzed by randomized\nblock analysis of variance (F = 1.95, df = 2,14, P = 0.18) .\nAs with FGE, four combinations of screen elevation and\noperating gate settings were tested using a 30% perforated plate\nporosity during the second summer series. Descaling averaged\n12.3, 9.0, and 2.9 in Slots 5B, 6B and 7B, respectively. Data\nwere adjusted for each set of extended-length screen conditions\nby subtracting the corresponding background mean (Slot 7B,\ncontrol) . Differences in mean descaling for the unadjusted and\nadjusted data were similar.\nDescaling results may have been affected by the presence of\nadult shad (Alosa sapidissima) in the catch during some tests,\nwhich appeared to increase the incidence of subyearling chinook\nsalmon descaling. For example, descaling with the extended-\nlength bar screen in Slot 6B averaged 5.0% (SE = 0.8) for tests\nwhen adult shad were not conspicuously present in the catch,\ncompared with 7.5% (SE = 1.4) when all data were included. The\nrandomized block analysis of variance procedure therefore\nincluded an adult shad covariate. However, none of the\ncombinations of operating gate position and screen elevation were\nsignificantly different for either the unadjusted (F = 0.00,\ndf = 1,14, P = 0.99) or the adjusted descaling data (F = 0.01,\ndf = 1,13, P = 0.93), regardless of the presence of adult shad.","26\nDescaling values for tests using a 30% porosity perforated\nplate were 13.7 and 9.6% for Slot 5B, and 7.7 and 7.0% for\nSlot 6B with no operating gate and partially raised operating\ngate conditions, respectively. When high numbers of adult shad\nwere not captured with the gatewell catch, descaling in Slot 6B\nwith a 30% porosity perforated plate was 5.0%, compared to a mean\nof 4.0% for the STS (control) in 7B. The differences were not\nsignificant (t = 0.49, df = 19, P = 0.63).\nOBJECTIVE 3: LEVELS OF SMOLTIFICATION\nIN YEARLING AND SUBYEARLING CHINOOK SALMON\nApproach\nFish were collected during FGE tests in Unit 5B and gill\nNa+-K+ ATPase levels were assayed to examine the relationship\nbetween FGE and physiological development. Twenty chinook salmon\nwere sampled from the gatewell (guided fish), with yearlings\nsampled during the spring and subyearlings during the summer.\nFish were placed on ice until gill samples could be taken. On\nthe same dates and during the same FGE tests, 20 fish were also\nrandomly sampled from the fyke-net catch (unguided fish) To\nensure that any observed differences in gill Na+-K+ ATPase\nbetween live gatewell and dead fyke-net fish were not caused by\ndeterioration of this enzyme in the dead fish, gatewell fish were\nkilled and placed in water at ambient river temperature until the\nfyke nets were removed from the water.\nGills that showed signs of excess deterioration were\ndiscarded. Fish were measured and gill filaments were trimmed\nfrom the gill arch and placed into 1.5-ml microcentrifuge tubes","27\nfilled with a buffer solution containing sucrose,\nethylenediamine, and imidazole (SEI) . Samples were immediately\nplaced in an ice chest containing dry ice and later stored in a\nfreezer and held at <-70°C until assayed. After gill removal,\nfish were individually stored in labeled plastic bags and placed\non dry ice for later analysis by the USFWS for BKD (results\nreported separately) Assays for gill Na+-K+ ATPase were\nconducted using procedures described by Zaugg (1982) with minor\nmodification.\nTo characterize the physiological status of the smolt\npopulation on each sample date, the mean Na+-K+ gill ATPase level\nwas determined for fish from the gatewell and fyke nets, weighted\nfor the number of fish captured, and averaged. Because FGE and\ndescaling tests often required important changes in guidance\nsystem components during the 1992 outmigrations, we did not\nattempt to identify correlations between physiological\ndevelopment and FGE. A paired t-test was used to test for\nseasonal differences in enzyme levels in guided vs. unguided\nfish.\nResults and Discussion\nYearling chinook salmon gill Na+-K+ ATPase activity changed\nlittle during the spring sampling period (Table 3 and Appendix\nTable 4) . Mean enzyme levels ranged from 29.3 to 35.5 umol P\nmg Prot-1 . h-superscript(1).

For\nthe first test date (25 June), subyearling chinook salmon gill\nNa+-K+ ATPase levels were the same for guided and unguided fish\n(t = 0.82, df = 30, P = 0.420) . .\nThe level of smolt development in yearling chinook salmon\nwas relatively high and constant during the 1992 outmigration at\nMcNary Dam, similar to the findings of Beeman et al. (1990) in\n1989. The high FGE values obtained throughout the spring\nindicated that the degree of smolt development would probably\nhave had little effect on yearling chinook salmon guidance with\nthe extended-length screen. With consistently high gill Na+-K+\nATPase levels and FGE values, a strong correlation would be\ndifficult to establish.\nCONCLUSIONS\n1) Extended-length submersible bar screens guided yearling and\nsubyearling chinook salmon and steelhead significantly better\nthan the STS at McNary Dam during spring and summer 1992.\nMean fish guidance efficiency values for extended-length\nscreens were 80 and 53% for the yearling and subyearling\nchinook salmon outmigrations, respectively, compared to 61 and\n30% for the STS.\n2) Lowering the extended-length bar screen 90 cm below the\nstandard elevation resulted in lower FGE because fish passed\nthrough the gap between the turbine intake ceiling and the\nscreen. Tests with a 60-cm lowered screen were limited in","30\nnumber and did not appear to provide benefit over the standard\nelevation.\n3) The extended-length bar screen at standard screen elevation,\nset at a 55° angle, with 30% perforated plate porosity, and a\npartially raised operating gate produced descaling rates\nsimilar to those with the STS for yearling chinook salmon\n(12.7 vs. 10.9%, respectively). These rates were lower than\ndescaling rates with other extended-length bar screen\nconfigurations. Fish guidance efficiency for yearling chinook\nsalmon was significantly higher with this extended-length bar\nscreen configuration than with the STS (80 vs. 71%)\n4) The extended-length bar screen at standard screen elevation,\nset at a 55° angle, with 30% perforated plate porosity, and no\noperating gate produced descaling rates for subyearling\nchinook salmon similar to descaling rates with the STS\n(6.6 vs. 5.1%, respectively). Fish guidance efficiency for\nsubyearling chinook salmon was significantly higher with this\nextended-length bar screen configuration than with the STS\n(53 vs. 33%) No other combination of screen elevation,\nperforated plate porosity, and operating gate setting provided\nsignificantly higher guidance or lower descaling.\n5) There was no significant difference in gill Na+-K+ ATPase\nlevels between guided and unguided yearling chinook salmon at\nMcNary Dam during spring 1992. During summer 1992, an\ninadequate sample size precluded a conclusion for subyearling\nchinook salmon.","31\nACKNOWLEDGMENTS\nWe wish to express our appreciation to our seasonal\nemployees for their interest and efforts during this project.
