density was formulated for the reach of stream surveyed. 

 Vegetation measurements were based on the following scale. 



1. Low = 0% - 3 0% ground cover 



2. medium = 31% - 70% ground cover 



3. high = 71% - 100% ground cover 



Habitat information was collected based on guidelines from 

 Idaho surveys (Wallen and Groves 1989) as follows: 



1. Dominant stream bank vegetation, 



herbaceous 



shrub 



tree 



2. availability of mid-stream loafing sites, 



low - sites / 10 m stream 

 medium - 1-3 sites / 10 m stream 

 high - > 3 sites / 10 m stream 



3. channel type, 

 meander 



Stream channel is located in a flat 

 bottomed valley with deep pools 

 separated by shallow riffles, the 

 channel appears to shift slightly 

 during each peak flow period. 



braided 



Stream channel is located in a flat 

 bottomed valley with shallow 

 channels and islands. The channel 

 may shift slightly during each peak 

 flow period. 



canyon 



Stream channel is structurally 

 controlled by a "v" shaped valley. 

 Rapids and runs characterize the 

 stream flow. Virtually no movement 

 of the channel occurs during peak 

 flow periods. 



channelized 



Stream channel is artificially 

 straightened by human activities,
