• Description:
  Smolt monitoring of juvenile salmonids was performed by the National Marine Fisheries Service at three key points in the Snake-Columbia River system for the Water Budget Center (WBC) during 1984; funding was provided by the Bonneville Power Administration. Smolt migrations were sampled at Lower Granite, McNary, and John Day Dams to provide data for evaluation of smolt survival, travel time, and migrational timing as required by the WBC. Primary objectives were to monitor and index juvenile salmonid passage at these three sites. At each site this involved: (1) monitoring the smolt migration from 1 April to 30 June at Lower Granite Dam, 10 April - 28 September at McNary Dam, and 3 April - 31 August at John Day Dam; (2) recovering and recording brands; (3) providing WBC with a daily and seasonal index of smolt passage at the dams, including numbers sampled and numbers collected for transport; and (4) providing WBC with daily and seasonal summaries of brand recapture information.
