The U.S. Army Corps of Engineers has awarded a US$3.1 million contract to Normandeau Associates Inc. to perform fish counting services at eight federal hydropower project along the Columbia and Snake rivers.
The Corps' Walla Walla District last solicited bids for the work in April.
Normandeau is to count adult fish passing through fish ladders at the 1,076.6-MW Bonneville, 1,780-MW Dalles, 2,160-MW John Day, 980-MW McNary, 603-MW Ice Harbor, 810-MW Lower Monumental, 810-MW Little Goose, and 810-MW Lower Granite facilities.
Fish counting is to produce technical information to help the Corps make engineering and operational decisions to provide safe, efficient fish passage through the migration corridor. Various groups and agencies also use fish counts for research in the basins.
