2011 Map of Winchester SW

About this map

Frenchman Hills Wasteway and the Winchester Wasteway dominate the drainage patterns of this central Washington landscape, illustrating the complex irrigation and water management infrastructure characteristic of the Columbia Basin. The map reveals a rigid grid of agricultural access roads, including Road K NW, Road J NW, and Road I NW, which divide the terrain into functional blocks for large-scale farming. This 2011 survey by the U.S. Geological Survey shows the intersection of modern transport and water control, with N Frontage Rd and Frontage Rd paralleling the primary highway corridor. The transition from the northern "NW" named roads to the southern "SW" designations like Road 1 SW and Road 2 SW centered on W Baseline Rd highlights the systematic land division of the region.
