Rock Creek, the largest tributary to the lower North Fork Blackfoot River, is a 2"^ order 

 stream that flows ~9 miles through public (State) and private ranch land. State land is only found 

 in the upper reaches of the stream. Rock Creek ranks high for all biological categories. These 

 ranks are due to 1) bull trout core area status, and bull trout rearing, 2) fluvial WSCT presence, 3) 

 high (multi-species) sport fishery value, 4) potential to increase flow in the Blackfoot River, and 

 5) high potential to improve downstream water quality. Rock Creek ranked low for social and 

 financial considerations. Rock Creek contains some rearing of bull trout, fluvial WSCT, brown 

 trout, rainbow trout and resident brook trout. Many of the fisheries impairments were addressed 

 over the last decade. Current fisheries impairments, concentrated in middle reach of Rock Creek 

 drainage, include 1) irrigation impacts (dewatering, entrainment, fish passage), 2) lack of 

 instream complexity, 3) heavily degraded riparian vegetation resulting from excessive livestock 

 access to stream banks, and 4) whirling disease.

Salmon Creek, a small, T' order outlet stream from Coppers Lake, flows ~2.5 miles in length 

 through entirely public (National Forest) private agricultural land before joining Dry Creek to 

 form Rock Creek. This small stream received mixed ranking for biological criteria including low 

 total rank, moderate biological rank and high ranks for native species and sport fishery values. 

 The overall low total rank is due generally to high native species and high sport fishery value 

 offset by low potential to improve on water quality and low rank for social/financial 

 considerations. Salmon Creek, located in the North Fork bull trout core area, supports very low 

 densities of both juvenile bull trout and fluvial WSCT along with high densities of brook trout. 

 Most of the habitat-related problems were corrected on Salmon Creek through extensive 

 restoration. Current Fisheries impairments, located on lower Salmon Creek instream flow 

 problems related to flood irrigation.
