About this map

Ochoco Reservoir dominates the central landscape of this 1990 survey, serving as a primary water management feature for the surrounding high desert terrain in Crook County. The engineering of the Ochoco Dam and its adjacent Spillway are clearly documented, along with the recreational infrastructure of Ochoco Lake State Park situated along the northern shore. The map illustrates the transition from the relatively level Combs Flat in the south to the rising elevations of the Ochoco Mountains and the Ochoco National Forest to the north and east.

Water drainage patterns are defined by several contributing tributaries, including Johnson Creek, Mill Creek, and Ochoco Creek. Land use is further noted by the presence of a Quarry and the clearly marked National Forest Boundary. This record reflects the area's geography just prior to more modern development, preserving the local road network and natural watercourses like Lawson Creek and Gravy Gulch.
