2023 Map of Winchester SW

About this map

Frenchman Hills Wasteway and Winchester Wasteway define this landscape within the t18n r25e and t19n r25e townships of Grant County. This modern survey illustrates the critical irrigation and drainage infrastructure supporting Washington's Columbia Basin. The network of frontage roads, including N Frontage Rd W and S Frontage Rd W, parallels the major east-west transportation corridor, while a grid of local routes like Ditch Rd and RD K SW provides access to the surrounding agricultural sections. The presence of these wasteways indicates a highly managed hydraulic environment where surplus irrigation water is channeled through the basin. Local researchers can trace the precise intersections of township lines and county roads that organize this rural landscape.
