Detailed analysis and studies are done to ensure the dam’s risk are not outside their recommended Dam Safety Public Protection Guidelines - December 2022.

The Conconully Dam structure is performing as designed. Reclamation and Okanogan Irrigation District are developing construction alternatives to modify and reduce risk at Conconully Dam in the event of an earthquake. Reclamation is committed to ensuring clear and open communication with downstream residents. As the project evolves, Reclamation will update the Dam Safety Process and Schedule >>
