Flat Creek Stream Restoration | Jackson, WY
CLIENT: Wyoming Game & Fish Department
PROJECT TYPE: Stream Assessments, River Restoration, Natural Channel Design, Aquatic Habitat Design, Permitting
PROJECT LOCATION: Jackson, WY
WaterVation, in partnership with Alder Environmental and Nelson Engineering is developing stream restoration plans for 6,200 feet of Flat Creek, just south of Jackson, Wyoming. This reach of Flat Creek has been subject to stream bank erosion, winter icing problems, stream warming, and stormwater runoff pollutants. The project proposes to remedy these factors by improving stream function and instream habitat for native Snake River Fine-Spotted cutthroat trout. WaterVation’s role on this project involves a comprehensive geomorphic assessment including BANCS mapping and stream survey of the project reach and reference reach. A detailed analysis of channel forming discharge was completing using reference reach data, stream gage records, and effective discharge calculations. This data was used to design the proposed channel dimension, pattern, and profile along with in-stream structures required for wintering habiatat, fish passage, and river stability. WaterVation is performing two-dimensional hydraulic modeling and sediment transport modeling to verify the design elements, habitat structures, in-stream stability structures, and riffle substrate materials. This data is used to support the natural channel design checklist and prove functional uplift.
