Lyle Adult Trap at Lyle Falls: Daily counts represent number of fish caught in the adult fish trap at Lyle Falls Fishway (Klickitat River RM 2.4). The updates included replacement of manually entered data from printed reports, the inclusion of historical data previously missing from DART, and the correction of counts that have been updated. On April 1, live fish counting resumes at all 8 Columbia River and Snake River Corps dams with fish ladders: from April through OctoberĮach year for 16 hours each day, fish counters working at each fish ladder look directly into the fish ladders to count the fish passing by.īonneville, The Dalles, John Day, McNary, Ice Harbor, Lower Monumental, Little Goose, and Lower Granite: On March 10, 2011, DART's Adult Passage data from the Army Corps dams-Bonneville, The Dalles, John Day, McNary, Ice Harbor, Lower Monumental, Little Goose, and Lower Granite-were updated in their entirety (1938-2011) to reflect the numbers currently reported by the US Army Corps Portland District. DART retrieves and posts the data as soon as it is made available.
Video tape takes at least a few days to process: the fish counters have to make, collect, and read the tapes, and then submit their fishĬounts.
