Abstract

Throughout Colorado many streams have already been impounded, and new reservoirs are currently in the planning stage. Previous research has shown that main stream reservoirs do change the composition and quality of the aquatic flora (Holmes & Whitton 1981; Lowe 1979; Marcus 1980; Lawson & Rushforth 1975; Ward 1982) which in turn affects the communities of aquatic fauna in regulated streams. However, detailed investigation of the influence of reservoirs on downstream algal communities in Colorado has only been accomplished for a site in the South Platte drainage system (Ward 1974). The present study of epilithic algae is part of a long-term effort to determine the effects of regulation on Colorado mountain streams. Zoobenthos data have been reported elsewhere (Zimmermann & Ward 1984).
