1967 Map of Diamond Swamp

USGS Topo · Published 1972

About this map

The Malheur National Wildlife Refuge dominates this 1967 survey, where the Donner und Blitzen River feeds an extensive network of human-made irrigation and drainage systems. This hydraulic landscape includes the Skunk Farm Canal, Diamond Canal, and Buena Vista Canal, which manage water across the Diamond Swamp and into the Malheur Lake alkali flat. The intersection of natural watercourses and structural engineering is evident at the Grain Camp Dam, while the Buena Vista Patrol Station serves as a lone administrative outpost in the valley.
