The irrigated landscape of central Washington is defined by the expansive Potholes Reservoir and the Winchester Wasteway, which dominate the southern half of this area. In the north, the small settlements of Mae and Mae Valley sit nestled within a grid of agricultural roads, including Mae Valley Rd NE and Stoneridge Rd NE. This modern survey illustrates the complex water management infrastructure essential to the region, featuring Canal W 20 and the distinct topography of Hiawatha Valley. The map details the transition from high-desert valley floors to the vast wetlands and inlets created by the reservoir system, providing a clear view of the rural homesteads and transport corridors that intersect the Columbia Basin Project's reach.
