Summary: The draft report and EA evaluates the impacts of constructing a one-mile long stone breakwater along the shoreline to reduce erosion which is imminently threatening the town’s sewage lagoons. In addition to shoreline erosion, reservoir filling and wind/wave and ice forces have caused habitat degradation which has negatively impacted Tribal members’ connection with the river and culturally significant natural resources. Solutions to restore ecosystem function were evaluated including constructing a 50-foot wide earth-filled island that would be planted with cottonwoods, willows, and various other plant species that are culturally significant to the Lower Brule Sioux Tribe. A shallow backwater/wetland would then be created between the island and the shoreline.
The proposed project would also include ancillary recreation features such as an access road, parking area, swim beach, boat ramp, staging area, vault toilets, picnic shelters and picnic tables, and a fish cleaning station.
Geographic Scope: Lower Brule, SD
