Proximity to roads from timber harvest also appears to contribute moderate levels of sediment to the channel. Elevation (ft) X1000 Fish Populations Population surveys (mile , and ) found only WSCT in Little Fish Creek. CPUE for WSCT decreased 96% from fish/100' in the upper section to fish/100" at the lower section (Figure 39). YOY densities were highest at the middle section and absent from the lower sample site (Appendix A). We collected 27 WSCT genetic samples from the three survey sections, the results of which are 2 3 stream Mileage Figure 40. Longitudinal profile for Snowbank Creek. Snowbank Creek Snowbank Creek is a 1^' order tributary to Copper Creek, which is an important spawning and rearing stream for fluvial WSCT and fluvial bull trout of the upper Blackfoot River. Snowbank Creek begins on the eastern slope of Stonewall Mountain and flows northeast miles through the Helena Nafional Forest before entering Copper Creek at mile Stream gradients range from 9107mile in upper reaches to 2207mile near the mouth (Figure 40). Our assessments focused on identifying restoration opportunities at a defunct diversion on lower Snowbank Creek. The diversion (mile ) was constructed in 1962 to divert water to create a put-and-take fishery at Snowbank Lake. In August 2003, we conducted fish population surveys immediately above and below the diversion (mile ) and near the mouth (mile ). Stream flow measurements were also taken in Snowbank Creek below the diversion and in the ditch. Of the total cfs, cfs was diverted to Snowbank Lake, leaving only cfs instream. Above the diversion, the stream cha
