Little Canyon Creek Subwatershed Steelhead Trout Habitat Improvement Project Sponsored by: Lewis Soil Conservation District
2
Columbia Country Safe Keeping Segment November 2003
3
Project Goal Improve steelhead trout habitat in Little Canyon Creek by implementing best management practices to upland agricultural lands.
4
Little Canyon Creek Watershed Big Canyon Creek Watershed Clearwater Subbasin
5
Little Canyon Creek 100% within Nez Perce Reservation 93% privately owned 60,200 acres 68% agricultural land use
7
Problems The only remaining steelhead trout runs in the Clearwater River subbasin, with limited or no hatchery influence, occur in the lower Clearwater River tributaries
8
Problems Limiting factors to steelhead habitat within Little Canyon Creek are associated with climate and land use patterns, including: – excess sediment delivery – flashy storm events – low sustained summer base flows Limiting factors to steelhead habitat within Little Canyon Creek are associated with climate and land use patterns, including: – excess sediment delivery – flashy storm events – low sustained summer base flows

Surface soil erosion is the dominant type of erosion from most cultivated lands in the watershed Source of sediment and water quality problems Sediment contributes to increased stream temperature and reduced stream productivity Surface soil erosion is the dominant type of erosion from most cultivated lands in the watershed Source of sediment and water quality problems Sediment contributes to increased stream temperature and reduced stream productivity Problems
10
Solutions To protect, enhance and/or restore fish habitat, best management practices should be developed and implemented on agricultural lands. To protect, enhance and/or restore fish habitat, best management practices should be developed and implemented on agricultural lands.
11
Solutions Best Management Practices –Combination of practices that effectively and practicably prevent or reduce the amount of sediment delivery to receiving streams –Techniques that will begin restoration and protection of aquatic habitat impacted by land management Best Management Practices –Combination of practices that effectively and practicably prevent or reduce the amount of sediment delivery to receiving streams –Techniques that will begin restoration and protection of aquatic habitat impacted by land management
12
Solutions Best Management Practices –Control and reduce erosion and subsequent sedimentation: Conservation tillage and no-till Grade stabilization structures Best Management Practices –Control and reduce erosion and subsequent sedimentation: Conservation tillage and no-till Grade stabilization structures

Hypothesis Hypothesis: Erosion and sedimentation is reduced from implementation of agricultural from implementation of agricultural BMPs BMPs Reduced sedimentation improves fish habitat habitat
