Union Creek, a primary 3'^ order tributary to the lower Blackfoot River, flows ~18 miles 

 through both public (BLM) and mainly private ranch land. The lower -15 miles of this stream 

 flows through private land. Union Creek ranks low in the total rank for project streams. The low 

 ranking results from a low native species rank, absence of sport fishery to the Blackfoot River, 

 and low rank for social and fmancial considerations. Because of its degraded condition, Union 

 Creek has high potential to improve water quality and increase flows to the Blackfoot River. 

 Union Creek contains both brook trout and WSCT. Brook trout are present in very low densities 

 in the middle reaches. Resident WSCT were sampled in low numbers in the middle and upper 

 reaches. Fisheries impairments, located in the middle and lower reaches include 1) poor road 

 crossings (undersize culvert), 2) irrigation impacts (low instream flows), 3) lack of instream 

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

 banks. Lower portions of Union Creek also appear to be undergoing channel incision.

Warren Creek, a small 2"** tributary to the middle Blackfoot River, flows -14 miles 

 primarily through forested foothills and private ranch land. Warren Creek ranks high in 

 the total rank for project streams. This high rank is due to high (multi-species) sport 

 fishery value to the Blackfoot River and high potential to improve downstream flow and 

 water quality. Warren Creek ranks low native species value. Warren Creek contains a 

 mixed species composition of brook trout, brown trout and low numbers of fluvial and 

 resident WSCT. Brook trout inhabit the entire drainage, brown trout are found in the 

 lower reaches and WSCT are present in the lower and upper reaches of Warren Creek. 

 Fisheries impairments, located throughout the drainage, include 1) poor road crossings, 2) 

 irrigation impacts (dewatering and passage), 3) channelization, 4) lack of instream 

 complexity, and 5) degraded riparian vegetation resulting from excessive livestock access 

 to stream banks.
