Shutts Flats Aquatic Resource Mitigation
for the Wyoming Department of Transporation
Previous impacts to the Shutts Flats area had resulted in a change of floodplain elevation, disconnecting it from the river. The Wyoming Department of Transportation retained Confluence to restore over 15 functional units by reconnecting the river to its floodplain.
The four main project elements included low-flow sedge benches, floodplain reconstruction, development of a wetland swale, and increased habitat diversity. In addition to conceptual design and a full PS&E package, we developed 1D and 2D hydraulic models of the mitigation site using HEC-RAS and a mitigation master plan.
We directly restored 2.5 acres of wetland habitat. Additionally, we restored hydrology to three more acres of decadent scrub-shrub wetland habitat.
