Thompson, R.F., Krebs, N.G., York, B.., and Molyneaux, B., 2019, Lower Brule Reservation Shoreline Erosion, Additional Data Layers, South Dakota, 2018: U.S. Geological Survey data release,


Additional data layers have been developed to supplement recently published information collected and developed for an investigation of shoreline erosion along the Lower Brule Reservation in Central South Dakota. The additional data layers presented in this data release include georeferenced 1965 single frame aerial photos, digitized shoreline features from the georeferenced 1965 images, digitized shoreline features from 2016 aerial imagery, and real-time kinematic surveys of shoreline features on selected reaches of the Lake Sharpe shoreline in 2018. This effort was completed by the USGS Dakota Water Science Center in cooperation with the Lower Brule Sioux Tribe, Tribal Preservation Office.

These data were collected and developed to allow additional estimates of shoreline erosion distances and rates to be computed for the Lower Brule Reservation. The 1965 shoreline approximates the position of the shoreline shortly after Lake Francis Case filled, while the 2016 shoreline represents most recent imagery available for the Reservation. The surveyed 2018 shoreline reaches include a portion of the previously-surveyed 7-mile reach near Lower Brule, and other selected shoreline reaches where irrigation systems are at risk due to shoreline erosion.
