Significant erosion along Lake Sharpe reservoir has occurred since the reservoir was formed in the 1960s. A major contributor to the shoreline erosion is ice shove, which is most severe when thick ice cover on the reservoir is combined with large wind events. One of the areas of highest concern for erosion induced by ice shove is located on the Lower Brule Sioux Reservation in South Dakota. Critical infrastructure is at risk for the Lower Brule Sioux Tribe as continual erosion occurs. This analysis estimates the ice shove forces due to wind and the water current along 10 miles of shoreline adjacent to the reservation. Additionally, this report discusses shoreline erosion mitigation measures.
