Summary
Built in 1888, this earth dam stands at a height of 13 feet and stretches 300 feet in length, with a capacity to store up to 60 acre-feet of water for irrigation and recreational purposes. The dam's hazard potential is classified as high, but its condition assessment remains satisfactory as of the last inspection in May 2021.
Despite its age, Clear Lake Dam continues to play a crucial role in water resource management in Chelan County, Washington. The dam's proximity to the city of Malaga and its recreational function make it a focal point for outdoor enthusiasts and climate advocates. With a normal storage capacity of 40 acre-feet and a maximum discharge of 50 cubic feet per second, the dam serves as a key component in supporting the local ecosystem and maintaining water quality in the region.
As a public utility structure, Clear Lake Dam not only ensures water availability for irrigation but also provides opportunities for leisure activities such as fishing and boating. Its strategic location within Congressional District 08, Washington, under the oversight of Representative Kim Schrier, highlights the importance of sustainable water management practices in the face of changing climate conditions. With regular inspections and enforcement measures in place, the dam stands as a reliable asset for water resource and climate enthusiasts seeking to protect and preserve the natural environment in Chelan, Washington.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
