Froelich Dam and its surrounding watershed define this portion of the Fort Yates District in Sioux County. The landscape is characterized by the prominent elevation of the Porcupine Hills in the southeast, contrasting with the lower drainage of Porcupine Cr which meanders through the northern sections. This topography informs the local road network, including Bia Rd 7 and Bia Rte 7, which navigate the rises and falls of the terrain.
