Juvenile coho, chinook, and rainbow trout/steelhead were sampled for the second and third consecutive years in Buck Creek using a rotary screw trap RST. The RST was sampled nightly to collect data on discharge, water temperature, and trap performance were collected throughout the studies. Fish captured were identified to species. Fork length and weight were recorded for all fish captured except lamprey, and scale samples were collected for a sub-sample of coho and rainbow trout/steelhead.
