2017 Map of Chapman Lake

About this map

Chapman Lake and Bonnie Lake anchor a landscape defined by the Channeled Scablands topography at the boundary of Spokane and Whitman counties. This 2017 survey details a sparsely populated region where water bodies like Badger Lake and Johnson Lake follow the northeast-to-southwest orientation of ancient glacial floods. The local transportation network relies on rural connectors such as S Cheney Plaza Rd and S Texas Ferry Rd, which navigate the coulees and basalt outcrops. Water drainage is managed by small tributaries including Sanders Cr, Rock Cr, and Buckeye Cr. The map illustrates how modern land use and road placement are still dictated by the distinctive geomorphology of the Columbia Plateau, with large tracts of land remaining largely undeveloped.
