The U.S. Geological Survey Dakota Water Science Center, in cooperation with the Lower Brule Sioux Tribe, have been collecting data to document shoreline erosion along Lake Sharpe and within the Lower Brule Reservation. This data release includes data collected and compiled from four efforts: shorelines were digitized from existing available maps and aerial imagery to record shoreline locations over time, trail cameras were used to automatically collect photos of the shoreline over time and create time-lapse videos, bank location surveys were completed at intervals to record changes in the location of the top of bank over time, and an unmanned aerial system (drone) was used to collect imagery that was used to generate a basemap of the Lake Sharpe shoreline near Lower Brule, South Dakota. These datasets and their associated metadata are being made available to the public through this data release.
