There are no tributaries with continuous surface water from the project or 

 burned area, to any fish bearing stream channels in the West Fork Ashby, 

 Dirty Dee, Wallace or Donovan Creek. 



Donovan Creek 



Surveys completed for Donovan Creek found westslope cutthroat and brook 

 trout present. In the upper portion of the watershed, only westslope cutthroat 

 were found. It is assumed that these populations are likely genetically pure. 

 Stream channel stability evaluations were taken on Donovan The evaluation 

 found that stream channel stability is good. The riparian areas are well 

 vegetated, providing bank stability and thermal protection for fish during 

 warm temperatures. Thick vegetation and undercut banks in the areas 

 observed during the channel stability rating are providing hiding cover for fish 

 and other aquatic organisms. In conclusion fish habitat is considered good 



Dirty Ike Creek 



Surveys completed in Dirty Ike Creek during 2002 found only westslope 

 cutthroat present. It is assumed that these populations are likely genetically 

 pure. 



Dirty Ike was evaluated for stream channel stability and was found to be in 

 good condition. The riparian areas are well vegetated, providing thermal 

 protection for fish during warm months and bank stability. Some increased 

 sediment levels were observed in reaches where poor road location or a road 

 crossing was, causing direct sediment delivery. In conclusion fish habitat is 

 considered good 



Wallace Creek 



Surveys completed in Wallace Creek in 2002 found westslope cutthroat 

 present in the lower portion of the watershed. It is assumed for the proposed 

 project that westslope cutthroat is present in other parts of the drainage where 

 sufficient habitat is present. Fish were observed during habitat assessments in 

 the middle portion of the drainage. The reaches of stream channel below the 

 project area are well vegetated and stream channel stability is good. Thick 

 vegetation, large woody debris and undercut banks in the areas observed 

 during the channel stability rating are providing hiding cover for fish and 

 other aquatic organisms, as well as habiatat complexity. In conclusion fish 

 habitat is considered good. There are reaches of Wallace creek where 

 vegetation and bank stability have been impacted by residential development 

 and mining. Some sections of Wallace Creek have high levels of increased 

 sediment and decreased channel stability as a result of residential development 

 and mining. Some potentially fish bearing sections of stream channel on State 

 and private ownership have culverts that could be fish passage barriers. 

 Increased sediment levels are expected in the section of stream channel below 

 the project area as a result of the wildfire.
