About this map

The Rocky Reach Dam serves as the focal point of this 1960s survey, illustrating the significant industrial and hydrological transformation along the Columbia River Lake Entiat. The map details the technical infrastructure of the site, including the Powerhouse, Substa, and Fish Ladder, alongside recreational and land management features like Turtle Rock and the Spawning Run.

Beyond the river, the landscape rises into the Entiat Mountains and the heavily ridged terrain of the Wenatchee National Forest. This document captures the transition from industrial utility at the river's edge, marked by Burlington Northern rail lines and various Borrow Pits, to the rugged wilderness of Burch Mountain and Prairie Canyon. Local landmarks such as Lincoln Rock and Baker Flats provide specific navigational points within this complex topography of canyons and springs.
