1977 Map of South Fork Reservoir

About this map

Malheur Cave stands as a primary landmark in this high desert landscape of eastern Oregon, situated near the upper reaches of the Malheur River. The topography of the late 1970s is defined by a sophisticated network of small-scale water management features, including the South Fork Reservoir and numerous smaller catchments like Browns Reservoir 4182, Red Mountain Reservoir, and Pollock Draw Reservoir. These scattered water sources underscore the necessity of water storage for ranching or land use in this arid environment.
