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

摘要

The biological significance of an increase in minimum streamflow in Douglas Creek, Wyoming, to brown trout (Salmo trutta) was assessed. Population and habitat data were compared between a period of minimum flow (1.0 cfs, 1972-76) and that of increased minimum flow (5.5 cfs, 1988-89). Brown trout standing stock increased two- to sixfold in different reaches of Douglas Creek between 1972 and 1988-89.
