The Fish Passage Center (FPC) provides current and historic data on salmon and steelhead passage in the main stem Snake and Columbia river basins. Data from the Smolt Monitoring Program (SMP) is intended to provide the information basis for federal, state and tribal recommendations for fish passage in the Federal Columbia River Hydro-electric System. Notes on the DART Adult Passage Dataset. USACE Dams Video and Live Counting: From November through March, video tape fish counting occurs at US Army Corps of Engineers dams with fish ladders on the Columbia and Snake Rivers. Fish counting by 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 fish counts.
The Portland District takes pride in its contributions to these U.S. Army Corps of Engineers achievements: Is the Nation’s number one federal provider of outdoor recreation. Serves as the Nation's environmental engineer. Owns and operates more than 600 dams. Operates and maintains 12,000 miles of commercial inland navigation channels. Due to network and cyber security issues, the U.S. Army Corps of Engineers can no longer host live video of fish at Bonneville Dam. Fish counts are available at the Fish Passage Center, DART and StreamNet websites.
The Columbia River Basin Fish Program is part of the Northwestern Division of the US Army Corps of Engineers, located in Portland, Ore., and provides improved coordination and communication among the Corps and state and federal agencies, tribes, the Northwest Power and Conservation Council, organizations, interest groups and the general public, on actions to improve salmon passage at Corps. The Corps relies on varied operational approaches including spill, turbine improvements, surface passage, bypass and fish transportation systems to address the impacts on fish populations from hydroelectric projects (which along with habitat, hatcheries and harvest, commonly referred to as the four H’s), for an effective fish restoration strategy.
May 04, 2012 · The concept has proved effective for adult fish passage. Juvenile Fish Passage at the Dams. Currently, juvenile fish can migrate past the dams by several routes: through the turbine; through the juvenile fish bypass system; or over the dam spillway. Some fish are transported past the dams by barge and truck under the juvenile fish. Adult Fish Passage There is one fish ladder for passing migratory fish with entrances on both shores and a fish channel through the dam that connects to the south shore ladder. Modifications to improve adult Pacific Lamprey passage include passage structures and installation of metal plating to assist lamprey upstream.
