2023 Map of Chapman Lake

About this map

Rock Creek carves a significant path through this portion of the Channeled Scablands, defining the drainage patterns and topography of the border between Spokane and Whitman counties. This contemporary survey illustrates the complex relationship between the water-rich depressions of Johnson Lake and the dry, basalt-etched plateaus that characterize the region. The landscape is interconnected by a network of long-established country roads such as W Chapman Lake Rd and S Cheney Plaza Rd, which navigate the coulees and scabland formations. Many of these routes, including S Texas Ferry Rd, follow historical corridors that have served the agricultural and transit needs of the Palouse and surrounding prairies for generations. The presence of smaller tributaries like Sanders Creek and Huckeye Creek underscores the intricate hydrology that remains central to this rural Washington environment.
