Dry Falls Dam

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.
