The seaward migration of salmonid smolts was monitored by the National Marine Fisheries Service (NMFS) at four sites on the Snake-Columbia River system. Sampling sites were Lower Granite, McNary, John Day and Bonneville Dams, and also included collection of data from NMFS research units sampling the bypass system in powerhouse No. 1 and No. 2 (PH No. 1, PH No. 2) at Bonneville Dam. Data from these sites provided information mainly for evaluation of smolt survival, travel time, migration timing and for water budget and spill management as required by Fish Passage Managers (FPM) and analysts of the FPC. To secure these data, it was necessary to monitor and index smolt passage which involved: (1) systematic sampling of the smolt migration from late March through July at Lower Granite Dam, late March through late October at McNary Dam, April through November at John Day Dam, and generally mid to late March through late November, depending on the sampling device(s) at Bonneville Dam; (2) recording brands; and (3) daily reporting of all pertinent fish capture and condition data, as well as dam operations and river flow data for passage estimates and travel indices to the FPC Fish Passage Data Information System (FPDIS). 7 refs., 2 figs., 1 tab.
