Dry Falls Dam, Embankment dam in Grant County, United States
Dry Falls Dam is an embankment dam in Grant County that diverts water from the Columbia River into Banks Lake. The structure channels flow across a wide footprint to serve irrigation needs for farming operations throughout the area.
The project emerged in the 1940s as part of a broader water management initiative for the Columbia Basin region. The dam was built to meet irrigation demands for agricultural expansion across central Washington.
The dam represents a major component of the Columbia Basin Project, transforming agricultural capabilities in central Washington through water management and distribution systems.
The dam is most accessible from land-based vantage points that provide views of the structure. Visitors should note this is an active work area where access may be restricted to certain zones.
The dam features a specialized reverse flow system that returns water to the Columbia River, generating additional electrical power during its operation.
