2017 Map of Umatilla

About this map

The Columbia River serves as the dominant geographical divide here, marking the boundary between Washington and Oregon. On the northern bank in Benton County, Plymouth and North McNary overlook the McNary Range Channel and Lake Wallula. To the south in Umatilla County, the city of Umatilla sits at the confluence where the Umatilla River feeds into the larger Columbia system. The landscape is defined by its complex water management infrastructure, featuring the W Extension Irrigation Canal, Brownell Ditch, and Umatilla Drain which support the surrounding agriculture. Genealogists can locate the Pioneer Memorial Cem and Sunset Hills Cem near the town center. The topographic survey also captures prominent local landmarks like Sillusi Butte and Umatilla Butte, alongside the transition from canyon terrain at Taylor Canyon to the managed pools of the river valley.
