. The Big Blackfoot River restoration progress report for 2002 and 2003 . Fish populations; Fishes; Fishery management; Trout fisheries; Stream ecology; Blackfoot River (Mont. ). a total barrier to upstream movements of WSCT. Wales Creek is one of the few streams in the Blackfoot Watershed where a significant amount of the watershed consists of weathered granite. Streams with this geologic composition are particularly vulnerable to sediment related impacts. In 2003, we began to assess Wales Creek from a restoration perspective. The assessment will carry into 2004 and focus on irrigation and instream flow needs, and determine if sufficient water is available for both. Fish Populations Wales Creek above the reservoir supports a native fish community of genetically pure WSCT and sculpins. Below the reservoir, Wales Creek supports WSCT. brown trout and very low rainbow trout densities near the mouth, hi 2003, we measured flows and completed fish population surveys above and below the reservoir, as well as in a small spring creek tributary to lower Wales Creek. Our flow measurements recorded 0.9 cfs above the reservoir (mile 2.6), no flow immediately below the reservoir (mile 1.9), 1.1 cfs at mile 0.3, and 1.0 cfs (mile 0.1) below a small spring creek near the mouth. Surveys showed higher densities of WSCT upstream of the reservoir (mile 2.6) than below the reservoir (mile 0.1), and the relative abundance of brown trout increased near the mouth (Figure 35). We captured brown trout and low densities of WSCT in the unnamed spring creek, with a combined CPUE of 6.6 fish/100'. Catch/100" Warren Creek Restoration Objectives: Restore riparian vegetation and stream habitat for all life stages of trout; improve spawning and rearing conditions; increase recruitment of trout to the middle Blackfoot River; reduce whirling disease infection levels. Project Summary Warren Creek, a small tributary to the middle Blackfoot River, originates on Ovando Mountain, flows 12 miles southw
