Nevada Spring Creek, a P' order spring creek tributary to lower Nevada Creek, flows ~3.2 

 miles in length exclusively though private ranch land. Nevada Spring Creek ranks low in all 

 biological categories, except for a high rank in water quality based on potential benefits in 

 restored condition. This low biological rank is due to low native species value and lack of a sport 

 fishery value. However, Nevada Spring Creek has potential to increase flow in the Blackfoot and 

 the high potential to improve downstream water quality to lower Nevada Creek and possibly the 

 Blackfoot River. Nevada Spring Creek supports very low densities of fluvial WSCT and brown 

 trout in the upper reaches. Fisheries impairments, located over the length of the stream include 1) 

 irrigation impacts (dewatering and fish passage), 2) channel alterations, 3) lacks instream 

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

 banks.

The North Fork Blackfoot River, the largest tributary (4* order) to the Blackfoot River, 

 drains the Scapegoat Wilderness before entering private land at river mile -17. The North Fork is 

 a number one ranked stream for project streams, in the total ranking. This rank is due to 1) bull 

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

 species) sport fishery value and high potential to increase flow in the Blackfoot. The North Fork 

 also has some potential to improve water quality by reducing sediment and temperature. The 

 North Fork supports one of the Blackfoot watersheds largest bull trout spawning populations. In 

 addition to native salmonids, the North Fork supports rainbow trout, brown trout and low 

 densities of resident brook trout. These species inhabit the river at a varying distribution at low to 

 moderate densities. Fisheries impairments confined to localized areas of middle reaches include 

 I) channel alterations, 2) lack of instream complexity, 3) degraded riparian vegetation, 4) and 

 reduced instream flow. Whirling disease is also present in the lower drainage.
