2017 Map of Winchester SW

About this map

Frenchman Hills Wasteway and the Winchester Wasteway define the drainage and irrigation patterns of this Grant County landscape. Set within the Columbia Basin, the area is meticulously organized by the Public Land Survey System, as seen in the grid of section lines across t18n r25e and t19n r25e. This systematic structure is mirrored in the local transportation network, where numbered and lettered thoroughfares like Rd 4 Sw and Rd K Nw provide access to the surrounding agricultural tracts. The interaction between the engineered water routes and the rigid road grid reflects the 20th-century development of this region for large-scale farming. Notable for its lack of concentrated settlements, the map instead highlights the vital role of infrastructure, including Ditch Rd, in managing the water resources necessary for the local economy.
