ABSTRACT: Streamflow on the Lower Osage River in Missouri is regulated by Bagnell Dam, a hydroelectric facility located 132 km upstream of the confluence with the Missouri River. The discharge released from the dam fluctuates daily and water depth can rise and fall 5 m, resulting in dynamic habitat conditions. This study used radio telemetry to track the daily movement of Spotted Bass and Shorthead Redhorse during high flow, low flow, and changing flow conditions. Twenty-three fish of each species were implanted with radio transmitters in March 2016 in a reach approximately 19 river km downstream of the dam. Fish movement was tracked by boat four times per month during daylight hours. Preliminary results from spring and summer 2016 show that the median movement rate of Spotted Bass was 11 m/hr in the spring and 16 m/hr in the summer. Shorthead Redhorse movement rates in the spring were 41 m/hr and were 23 m/hr in the summer. Movement rate and displacement varied between individual fish within both species and was highly variable among flow conditions. The results of this study can be used to determine the impacts of season and discharge on fish movement in the Lower Osage River and can inform managers about fish response to environmental change.
