2023 Map of Sanderson Creek

About this map

The Columbia River forms the eastern boundary of this high-plateau landscape, marking the transition from Douglas County to Okanogan County. The river's path is defined by a series of significant whitewater features including Nespelem Rapids, Equilibrium Rapids, and Monaghan Rapids, which dictate the topography of the surrounding Deep Canyon and Bailey Basin. In the western portion of the quadrangle, the land is characterized by numerous small basins and drainages, such as the areas around Sanderson Creek and School Creek. Local hydrology is dotted with small bodies of water like Smith Lake and Rock Lake. The landscape is largely defined by the agricultural and ranching grid, with a network of local thoroughfares including Pendell Rd and Cunningham Rd providing access to the various canyons and bars along the river's edge.
