FISHERIES 



No bull trout or migratory cutthroat 

 trout inhabit streams in the project 

 area. Eastern brook trout, an exotic 

 species, are present in streams in 

 the project area. 



ALTERNATIVE EFFECTS 



SEDIMENT DELIVERY 



Direct and Indirect Effects 



• Direct and Indirect Effects ofA'o-. Action 

 *1lternntive .1 on Sediment Delicery 



No-Action Alternative A would have 

 no direct effects to sediment 

 delivery beyond those currently 

 occurring. Existing sources of 

 sediment, both in-channel and out 

 of channel, would continue to 

 recover or degrade based on natural 

 or preexisting conditions. 



The indirect effects of No-Action 

 Alternative A would be an increased 

 risk of sediment delivery to 

 streams from crossings that do not 

 meet applicable BMPs . These sites 

 would continue to pose a risk of 

 sediment delivery to streams until 

 other funding became available to 

 repair them.

Action Alternative B would replace 

 several stream crossings in the Dog 

 Creek watershed and along the 

 proposed haul route. The crossings 

 proposed for replacement do not 

 currently meet all applicable BMPs 

 and require a new culvert in order 

 to meet applicable standards. The 

 replacement of existing stream 

 crossings would contribute sediment 

 directly to Dog Creek. This 

 sediment would be minimized through 

 application of standard erosion- 

 control measures. The sediment 

 delivery anticipated from this 

 project would be short term and 

 comply with all applicable permits 

 and State water-quality laws. In 

 addition, several sites would have 

 additional erosion control added to 

 lower the risk of sediment delivery 



to a stream or draw. In some 

 cases, the addition of erosion- 

 control measures may increase the 

 risk of sediment delivery in the 

 short term by creating bare soil. 

 However, as these sites revegetate, 

 the long-term risk of sedimentation 

 to a stream would be reduced to 

 levels lower than the existing 

 condition. 



Action Alternative B would also 

 construct 0.2 miles of temporary 

 road in Section 2 8 of the proposed 

 project area. This temporary road 

 would require installation of a 

 temporary stream crossing on a 

 perennial stream in the Dog Creek 

 watershed. This stream has, 

 approximately, a 5-foot bankfull 

 channel and flows through a series 

 of wetlands before reaching Dog 

 Creek. Installation of this 

 crossing would involve placing a 

 bundle of well-casing pipes in the 

 channel; the pipe bundle would be 

 wrapped in filter fabric. All 

 materials would be removed 

 following the completion of 

 harvesting activities. This 

 installation would create sediment 

 delivery to the creek during the 

 course of construction and hauling. 

 Sediment delivery is expected to be 

 very minimal since little or no 

 bank and bed disturbance would 

 occur from placement of the well 

 casings. Sediment generated from 

 traffic would be minimized by the 

 application of erosion-control 

 measures. Reclamation of the 

 temporary road and crossing would 

 occur immediately following 

 completion of activities in the 

 proposed units. The reclaimed road 

 would present an increased risk of 

 sediment delivery until bare soil 

 is revegetated. 



Action Alternative B would have a 

 very low risk of sediment delivery 

 to streams as a result of the 

 proposed timber-harvesting 

 activities. Some harvesting 

 activities may occur within 

 designated SMZs. This harvesting 

 activity would follow all
