Summary

Completed in 1932, the earth dam stands at a height of 13 feet and stretches 158 feet in length along the Cle Elum River. Owned and funded by the Bureau of Reclamation, the dike serves a vital purpose in controlling water flow and providing a storage capacity of 437,000 acre-feet.

With a low hazard potential, Cle Elum Dike 1 has not undergone a recent condition assessment, but it is inspected annually by the Bureau of Reclamation. The associated structures include WA00274S001, WA00274S003, and WA00274S004. While the dam does not have a spillway or outlet gates, it plays a crucial role in managing water resources and mitigating flood risks in the Kittitas County area. In the event of an emergency, an Emergency Action Plan (EAP) is in place, with the last revision made in June 2020.

Overall, Cle Elum Dike 1 stands as a testament to effective water resource management and infrastructure development. As a key component of the region's flood control system, the dam plays a vital role in safeguarding communities and ecosystems along the Cle Elum River. With its historical significance and ongoing maintenance by the Bureau of Reclamation, the dike continues to be a critical asset in ensuring water security and climate resilience in the area.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
