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 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.
