Service (NMFS) to research and develop a passive integrated transponder (PIT) tag for use in the Columbia River Basin (CRB) Fish and Wildlife (F&W) Program, The PIT tag system enables large amounts of data to be produced using relatively few tags, compared to traditional tagging and marking systems. PIT-Tag Detection System for Large-Diameter Juvenile Fish Bypass Pipes at Columbia River Basin Hydroelectric Dams Article (PDF Available) in North American Journal of Fisheries Management 25(2. The Columbia River PIT Tag Information System (PTAGIS) is a data collection, distribution and coordination project. The project saw over 1,, juvenile salmonids marked with passive integrated transponder (PIT) tags, for the out-migration through the Columbia and Snake River systems, compared to over 1,, in (Tables 1 & 2). Based on the success of the first two full-flow PIT-tag systems, similarly designed full-flow systems were installed at Bonneville, John Day, Lower Monumental, and Little Goose Dams between

In the spring of and , a prototype kHz flat-plate (pass-by) passive integrated transponder tag interrogation (PIT tag) system was installed at the terminus of the downstream migrant (DSM) channel of the Bonneville Dam First Powerhouse, located on the Columbia by: The DART PIT Tag Adult Returns Conversion Rate Report (based on selections made for Wells (Columbia River), Lower Granite (Snake River), Prosser (Yakima), and Three Miles Falls (Umatilla). Indicates that the results include fish that were detected at an interrogation site upstream from the upper project, but were not detected at the upper. Barila ). Bypass systems at most dams on the Snake and Columbia rivers are equipped with pas-sive integrated transponder (PIT) tag detection systems, where fish are passively interrogated for PIT tags as they pass (Prentice et al. b; Muir et al., in press). Methods Tagging procedures.—Actively migrating fish. publicly available real-time temperature data collected between and at Columbia and Snake river dams Model input data are listed in Appendix A: “Sources of Data.” We investigated the impacts of the four Lower Snake River dams on river temperature by running the RBM model with, and without, the four reservoirs.

  Recent tests show fish passage improvements at all eight federal dams on the lower Columbia and Snake rivers have dramatically increased survival rates for juvenile salmon and steelhead listed. 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. The Columbia Snake River System is a mile river highway that provides farmers and other producers access to international markets. The Snake River dams play a crucial role in support of the overall river system. In , 4,, tons of cargo were barged on the Snake River. It would have ta rail cars to carry this cargo.
