Brown Trout Population and Habitat Changes Associated with Increased Minimum Low Flows in Douglas Creek, Wyoming.

Abstract : We assessed the biological significance of an increase in minimum flow to the brown trout (Salmo trutta) population in Douglas Creek, Wyoming. Douglas Creek is a regulated stream that underwent an increase in the required minimum flow in 1986. We compared population and habitat data obtained during the period when minimum flow was 1.0 cubic feet per second with data collected after the minimum flow was increased to 5.5 cubic feet per second. Our goal was to investigate the response of the brown trout population in Douglas Creek to an increase in the minimum flow release.
