Popis:	Our objective was to determine if salmonid biomass across a large watershed in the Bighorn Mountains of Wyoming was influenced by stream size, channel slope, or abundance of pool habitat. No relationships were observed with wetted width or channel slope; however, a significant relationship was found between biomass and the abundance of pool habitat. These results suggest that geomorphic stream features had little influence on salmonid biomass, but that instream habitat was important. This pattern may occur in other montane watersheds where streams originate primarily from groundwater sources in limestone formations.
