KAT - Kalama River Trap Antenna
Status: Active - Operations UnspecifiedGeneral Operational Period: Seasonally
Start Date:
PIT antenna located on the upstream release pipe of the Kalama River Trap. The fish trap is operated seasonally (July - October) in conjunction with the adjacent weir. The Kalama River supports several populations of ESA-listed salmon and steelhead, with PIT tags being implanted in out-migrating steelhead and spring Chinook salmon smolts. This PIT array will: 1) enhance our understanding of how the weir affects migration, 2) provide infrastructure to further evaluate fish ladder use at the upstream Kalama Falls Hatchery fish barrier, and 3) serve a staple of the ongoing lifecycle monitoring program on the Kalama River.
