dc.description.abstract The Pelton Round Butte Hydroelectric Project (Oregon) was built between 1957 and 1964. As a result the anadromous steelhead trout was extirpated from the upper Deschutes Basin by 1968. The Deschutes Basin is a model for instream flow restoration projects in the Pacific Northwest that are largely driven by the reintroduction of anadromous steelhead trout into the upper Deschutes Basin and in particular have focused on Whychus Creek Watershed. Current instream flow restoration targets for Whychus Creek are based on certified instream water rights, derived from habitat surveys. This paper quantifies instream flow restoration targets for Whychus Creek based upon flow, temperature, and estimated steelhead trout carrying capacity. It is suggested that instream flow restoration targets are not fully resolved and additional flows may be needed to meet a restoration goal for temperature in Whychus Creek. It is proposed that estimates of steelhead trout carrying capacity that are based upon the Upper John Day Subbasin steelhead trout densities are an appropriate measure of potential steelhead trout numbers within Whychus Creek and are appropriate for refining instream flow restoration targets. en_US
