Franklin D Roosevelt Lake dominates this landscape, where the waters of the Columbia River and the Sanpoil River converge. The topography is defined by the steep-walled Penix Canyon and Speigle Canyon, which cut through the high ground south of the reservoir. This area is divided by the Colville Indian Reservation boundary to the north and the expansive Coulee Dam National Recreation Area, highlighting the intersection of tribal lands and federal recreational management.
