2024 Map of Irrigon

About this map

Irrigon stands as the primary settlement on this stretch of the Columbia River, where the high desert meets the modern engineered landscape of the Pacific Northwest. The town's grid is bounded by the West Extension Irrigation Canal, a vital water artery that enabled the region's agricultural development. To the north, the river expands into Lake Umatilla, a massive reservoir created by downstream dams, which now covers much of the historic shoreline. This survey captures the intersection of multiple jurisdictional boundaries, including the state line between Washington and Oregon and the convergence of Benton, Morrow, and Umatilla counties.
