Umatilla and the surrounding Columbia River borderlands are defined by an intricate network of water management and mid-century settlement patterns. The river landscape is partitioned by the McNary Range Channel and Lake Umatilla, with the Umatilla Bridge providing a critical link across the state line to Plymouth, Washington. The map details a specialized irrigation infrastructure essential to this arid region, featuring the W Extension Irrigation Canal, Brownell Ditch, and several laterals like the OA Lateral.
