Projects>Swamp Creek Riparian Restoration

Confluence completed a comprehensive survey and developed designs for restoring aquatic and riparian habitat on the lower 6.75 miles of Swamp Creek. Originating in the Beaverhead mountains and flowing northeast across the Big Hole Valley, Swamp Creek was traditionally a stronghold for all life stages of adult grayling outside of spawning seasons. Recent surveys had indicated reduced use of the creek by adult grayling outside of spawning seasons. Confluence’s design included relocating one-half mile of Swamp Creek to its historic configuration in order to immediately provide superior habitat, stable banks, and improved woody cover. The historic channel, which was previously active in the 1940’s, had mostly filled in with silt, sand, and vegetation. Confluence’s work has reactivated the channel back to its historic dimensions. A series of plugs was shaped across the deactivated channel using fill material, resulting in a series of wetland ponds. Over 600 mature willows and an acre of wetland sod were designed and landscaped in the project.
