b) Cumulative Watershed Effects-Estimated increases in annual water yield in those 



watersheds contained within the Dirty Ike Salvage project area as a result of the Dirty Ike 

 fire are as follows: 



While the WYl in some of these drainages, post-fire, exceeds the DNRC's allowable 

 increase of 15%; the proposed action will have minimal effects on water quality for the 

 following reasons: 



• Ashby Creek -The burned area is located in the top of the drainage and neither of 

 the Class II stream channels in the burned area have continuous flow to another 

 body of water. 



• EHrty Ike and Donovan Creeks -Sediment yields are expected to increase, but 

 should be minimal as a result of the lack of live stream channels in the project 

 area. 



• Wallace Creek -Post-fire and post-salvage harvest WYl is below 15%. 



c) Soils-The implementation of recommended mitigation measures within harvest units 

 should not increase erosion rates beyond those expected within burned areas not planned 

 for harvest operations. These mitigations would include adherence to BMPs, season of use 

 limitations and slope restrictions (i.e. no ground-based skidding on slopes greater than 

 40%). In addition, 5-10 tons of coarse (> 3" diameter) woody debris would be left on the 

 ground for nutrient cycling and erosion control. No additional cumulative impacts to the 

 soil resource are expected as a result of the proposed activities. 



d) Cold Water Fisheries -There are no fish bearing streams located in the projea area in 

 Ashby, Donovan, or Dirty Ike Creeks. Wallace Creek is the only fish-bearing stream 

 located near the projea area. As there will not be any harvesting in or near Wallace 

 Creek, the implementation of recommended harvest mitigations should minimize any 

 impacts to this fishery. No additional cumulative impacts to cold-water fisheries are 

 expected as a result of the proposed activities. 



e) Noxious Weeds -Equipment will be cleaned prior to entering the project area, which will 

 reduce the likelihood of weed seeds being introduced onto treated areas. The DNRC will
