hummiKking was especially noticeable below the lower pool area where the cows have a stream 

 crossing. 



Reach Riparian Ranking: BLM= 66.7% (16 or24) EPA RBP= 63% (126 of 200) 



Reach Riparian (Jcomorphology: Hie geomorphology of this stream reach is a Rosgen F-6 with a 

 gentle slope (<1%), moderate sinuosity, a run-pool contluuration with silt-dominated pools. Pools are 

 slightly incised and averaged -25 cm in depth, wetted width of the reach averaged 4.5 ni. Surrounding 

 bank materials are coarser than the channel bed materials indicating an accumulation of sediments in the 

 reach. 



Amphibian C ommunity: 1 5-20 adult Northern Leopard Frogs (NLF) were present. No tadpoles were 

 present in pool. 



Fish Community: i fish species was seined in the pool, none in the run. Only species was the fathead 

 minnow. Lxpected Ush for this stream type (D005 trending toward H005) have been met. 



Fish Community Quality: 1B1= 44.77 0/E= 1/1.4 or 71% of the expected reference fish. 



.Vlacroinvertcbrate Community: This community of intermittent prairie stream invertebrates consists 

 of the Prairie Pool assemblage (#12. Stagliano 2005). The community indicator species are characterized 



bv tolerant, damsel flv taxa. Cocncii^rion Ftnillcii^md sp. Eiuilluiinm civile. Lcslcs ami Ishmira. the 

 crustaceans (Uyatclla ami Gamnuirus), many genera and species of the water boatman (Corixidae: 

 Sij^ara alternate. Trichocorixa nais. and Corisetla\ the snails (Physella. Gyraulus. and Stagnicola), 

 mayflies (Caenis and Callihaclis). and beetles (Oreodytes. l.accophilus. Hydroporns and Hygrotus). 

 As the complexity of the pool habitat decreases the dinger habitat species are lost, such as the 

 damseltlies and many of the water boatman taxa. Only 50% of the indicator species were present in this 

 sample for a D005 stream type indicating slight impairment. The Montana MMl ranks the community as 

 slightly impaired as well.
