2021 Map of Allan Dam

About this map

Little White River meanders across the northern portion of this landscape in Bennett County, defining the drainage patterns of the High Plains. The terrain is characterized by a series of ephemeral and perennial watercourses, including Heckel Cr and Bear Cr, which carve through the topographical contours. The presence of White Lake and Lake Cr provides a focal point for the local hydrology within the township and range system. This 2021 survey by the U.S. Geological Survey reflects the enduring rural character of the region, where the land is largely defined by its natural water features rather than dense settlement. The map serves as a primary record of the modern hydrological state of these specific South Dakota tributaries before they join larger river systems to the east.
