About this map

The Yakima Valley floor meets the sharp ascent of Toppenish Ridge in this survey of south-central Washington. The northern half of the landscape is defined by an intensive network of irrigation and drainage infrastructure, including the Marion Drain, Unit 2 Canal, and numerous engineered waterways like the E Island Lateral and Piute Lateral. These features support the agricultural character of the region, where roads like Harrah Drain Rd and Lateral C Rd follow the strict cardinal grid of the section lines. To the south, the terrain shifts dramatically as the land rises toward the crest of the ridge. This higher elevation is marked by natural features such as Oak Spring and the winding course of Toppenish Creek, which contrasts with the straight-line geometry of the valley's managed water systems.
