2014 Map of Winchester SW

About this map

Frenchman Hills Wasteway and Winchester Wasteway define the hydrological character of this portion of Grant County, where water management infrastructure supports the agricultural landscape of the Columbia Basin. The terrain is structured by an orderly grid of rural routes, including W Baseline Rd and a series of numbered paths like Road 1 SW and Road 4 SW. The east-west corridor of Interstate 90 and its accompanying N Frontage Rd bisect the northern sections, marking the primary transportation artery through the region. Land divisions are clearly delineated by township and range markers such as t18n r25e, illustrating the systematic organization of Washington's central plains. The presence of the Ditch Rd and the prominent wasteways highlights the vital role of irrigation and drainage in this environment.
