2024 Map of Umatilla

About this map

Umatilla and its surrounding communities sit at a critical hydrological junction where the Umatilla River joins the Columbia River, creating a landscape defined by water management and transit. The area is partitioned by massive reservoirs, including Lake Wallula and Lake Umatilla, which are linked by the McNary Range Channel. On the Washington side, the settlement of Plymouth overlooks the water, while the Oregon shore is a complex network of industrial and residential zones like Power City, McNary, and Charlestown. The reliance on irrigation is evident in the sprawling reach of the West Extension Irrigation Canal, the Brownell Ditch, and various laterals such as the OA Lateral and OB Lateral. Local history is anchored by the Pioneer Memorial Cem and Sunset Hills Cem, while the rugged geography is marked by prominent elevations like Sillusi Butte and Umatilla Butte.
