Rocky Reach Dam dominates this section of the Columbia River, where hydroelectric infrastructure and resource management define the landscape. The river, widened into Lake Entiat behind the dam, serves as a hub for both industry and conservation, featuring a powerhouse, several substations, and a dedicated fish holding pond with a spawning run. This 2003 revision reveals the complex coordination between the Wenatchee National Forest and the State Wildlife Area, highlighting the intersection of industrial power generation and wildlife preservation.
