Limiting factors within the project area include reduced floodplain connectivity, altered flow regime, livestock and wildlife impacts, recreation impacts, infrastructure and environmental conditions. Within the project reach Geum evaluated existing riparian vegetation communities and river geomorphology to understand limiting factors that can be addressed through restoration or management actions. The project area encompasses a 27.5 mile reach that extends from the US 87 bridge just downstream from Earthquake Lake to the Varney Bridge about eight miles upstream from Ennis. This document serves to guide management and restoration planning decisions with the vision of restoring and enhancing the river’s riparian, wetland, and aquatic habitats to promote ecological resilience for generations to come. To help support its mission of protecting the unique Madison River and its high quality fishery, the Madison River Foundation contracted with Geum to develop a Riparian Restoration Master Plan to guide restoration opportunities along the river corridor. Construction of the project has not yet started. The desired future condition for the Lower Crooked River is a more natural landscape that maximizes ecological site potential by restoring native riparian plant communities, providing preferred habitat for native aquatic and terrestrial species, and by establishing sustainable river and floodplain morphology. to develop a restoration and rehabilitation design for the lower two miles of Crooked River. and TerraGraphics Environmental Engineering, Inc. Between 20, Geum teamed with River Design Group Inc. Forest Service Nez Perce National Forest are leading efforts to improve ecosystem conditions in the South Fork Clearwater Subbasin and rehabilitation of the lower Crooked River Valley is part of that effort. These physical changes to the valley bottom altered stream and riparian processes, and have affected aquatic and terrestrial habitat conditions, resulting in degraded ecosystem conditions relative to historical conditions. Between the 1930s and 1950s the lower Crooked River Valley was heavily impacted by dredge mining leaving behind large tailing piles and deep ponds throughout the valley bottom.
