1988 Map of Thompson Reservoir

USGS Topo · Published 1988

About this map

Thompson Reservoir dominates this landscape within the Fremont National Forest, serving as a central hub for water and recreation in high-desert Oregon during the late 1980s. The map illustrates a developed recreation infrastructure, including the Thompson Reservoir Campground, the East Bay Campground, and multiple boat ramps. A significant historical line, the Indian Treaty Boundary, cuts through the southwestern corner of the sheet, dividing the terrain near Indian Creek Flat and Silver Creek. This survey captures the region's ranching and natural resource management through numerous Stock Ponds, various Cinder Pit locations, and named springs like Squaw Spring. The topography transitions from the alluvial bottom of Thompson Valley to prominent heights such as Sycan Butte and Brattain Ridge, offering a clear view of the drainage patterns of Auger Creek and Graham Creek.
