2023 Map of Rocky Reach Dam

About this map

The Columbia River dominates this landscape north of Wenatchee, where it serves as the boundary between Chelan and Douglas counties. This 2023 survey centers on the Rocky Reach Dam, an essential piece of hydroelectric infrastructure that regulates the Rock Island Pool and created the upstream Lake Entiat. On the river's western bank, the rugged foothills of the Entiat Mountains rise toward Burch Mtn and Dinkelman Ridge, deeply incised by drainages like Swakane Creek and Spencer Canyon. Residential growth is evident in settlements like Sunnyslope and the level orchard grounds of Baker Flats. Much of the northern and western terrain remains protected within the Wenatchee National Forest, reflecting the region's balance between industrial energy production and the preservation of the Cascade foothills. Notable geological landmarks like Lincoln Rock and Turtle Rock punctuate the river's path, marking the transition from the high desert to the mountain slopes.
