1989 Map of Sanderson Creek

About this map

Colville Indian Reservation land meets the eastern bank of the Columbia River-Rufus Woods Lake in this late-twentieth-century study of the boundary between Douglas and Okanogan Counties. The landscape is defined by the heavy drainage patterns of several seasonal and perennial waterways, including Sanderson Creek, Moses Creek, and China Creek, which carve through the plateau toward the river. High-country water bodies like Black Lake and Smith Lake are prominent landmarks within this sparsely developed terrain, where the absence of major towns highlights the importance of localized features like Schoolhouse Creek. The map records a specific moment in the river's history after the creation of Rufus Woods Lake, showing the relationship between the Reservation Boundary and the shoreline at Buckley Bar and Deep Canyon.
