Richland, Wash. – In Spring 2013, the U.S. Army Corps of Engineers selected Environmental Assessment Services, working with Normandeau Associates, to provide adult fish counting services at mainstem dams with fish passage facilities on the Columbia and Snake rivers.

EAS staff will continue to take daily fish counts of adult salmon, steelhead, shad, lamprey, and other migrating and resident species as they pass through counting stations at the dams. Ongoing data on the status of fish that pass through the dams are required to evaluate the status of fish stocks, particularly threatened and endangered species. EAS’s fish passage work assists federal, state, and tribal governments protect and restore targeted species.
