Forty radio frequency and 120 standard type Floy tags were attached to smallmouth bass to monitor their movements in connection with Columbia River water level fluctuations. Tagging information provided data on bass movement during and after their spawning period as well as their location and habitat preference. Field data indicated spawning occurred from April through June with bass leaving backwater areas and returning to the main stem of the Columbia River in August 1976 and late June 1977. River movement appeared to be related to water depth, current, and available forage. Radio-tagged fish were monitored a maximum of 61 km and Floy tags were returned by fisherman from as far as 63 km. Spawning success was estimated for White Bluffs, Hanford and F Area sloughs during 1976 and 1977 and appeared to be related to water level fluctuations. Loss of bass because of entrapment, predation, thermal or oxygen stress, and desiccation was observed in several temporary ponds.
