About this map

The Rocky Reach Dam dominates the central corridor of this reach of the Columbia River, where the massive hydroelectric structure spans the water near the settlement of Zena. The surrounding Chelan County landscape is defined by the dramatic descent of Swakane Canyon and Tenas George Canyon toward the river's edge. This 2011 survey documents the engineered shoreline and recreational areas, including the Prairie Spring Campground and landmarks like Lincoln Rock.

A network of mountain roads such as Burch Mountain Rd and Entiat Summit Rd provides access to the high ground above the river valley. To the north, Spencer Lake and multiple springs like Prairie Spring and Rattlesnake Spring dot the terrain. The presence of Turtle Rock within the river channel illustrates the geological character of the Columbia prior to and following the dam's modern influence on the water level.
