Monture Creek, a large 4* order tributary to the middle Blackfoot River, originates in a 

 roadless watershed along southern flanks of the Bob Marshall Wilderness. Monture Creek is -24 

 miles long, with the lower ~12 miles flowing through private ranch land. Monture Creek, located 

 in the bull trout core area, ranked as a very high priority for all criteria. This ranking is due to 1 ) 

 bull trout spawning, rearing and core area status, 2) presence of fluvial WSCT, 3) a high (multi- 

 species) sport fishery value, 4) high potential to improve water quality in the Blackfoot River, and 

 cooperative lands resulting in a high ranking for the social category. Monture Creek, a primary 

 spawning and rearing stream to the middle Blackfoot River, supports populations of fluvial bull, ^ , 

 fluvial WSCT, rainbow trout and brown trout and resident brook trout. Most fisheries 

 impairments for Monture Creek were corrected over the last decade. However localized 

 impairments in the lower Monture Creek include 1) channel alterations, 2) lack of instream -, 

 complexity, 3) degraded riparian vegetation, 4) livestock access to the stream banks and 5) a low- 

 level infection of whirling disease. ,t

Nevada Creek below the reservoir is a ' "^^ 



large 3 order tributary to the middle Blackfoot River that flows ~33 miles exclusively through 

 private ranch land. Lower Nevada Creek ranks very low in all criteria except for potential water . 

 quality benefits where it ranks high. These low ranks are due to the lack of native species and 

 lack of a sport fishery values to the Blackfoot River. Although Nevada Creek ranks low overall, 

 it ranked high for potential to increase flow to the Blackfoot, and ranked high in potential to , 

 improve downstream water quality. Salmonids (rainbow trout and brown trout) inhabit lower 

 Nevada Creek in very low densities immediately below Nevada Creek reservoir, but absent from 

 lower Nevada Creek. Fisheries-related impairments, located throughout the drainage, include 1) 

 irrigation impacts (entrainment, dewatering), 2) channel alterations, 3) lack of instream 

 complexity, 4) degraded riparian vegetation resulting from excessive livestock access to riparian 

 areas, and 5) low water quality.
