Summary

Constructed in 1956 by the DOI Bureau of Reclamation, this earth dam stands at 38 feet in height, with a storage capacity of 119,600 acre-feet and a surface area of 4,008 acres. The lake's primary purpose is irrigation, but it also provides opportunities for recreational activities such as fishing and boating.

Situated in Klamath County, Crescent Lake is regulated by the Oregon Water Resources Department and undergoes regular inspections to ensure its proper functioning. With a high hazard potential but a satisfactory condition assessment as of October 2020, the dam features a slide (sluice gate) outlet for water management. The lake's scenic location and its role in supporting agriculture and recreation make it a vital resource for the community and a focal point for water resource and climate enthusiasts.

Overall, Crescent Lake is a crucial water body in Oregon that serves both practical and leisure purposes. Its management, maintenance, and regulatory oversight ensure its continued contribution to irrigation, recreation, and the local ecosystem. With its impressive infrastructure and strategic location, Crescent Lake remains a valuable asset for the region's water resource management efforts and a beloved destination for outdoor enthusiasts.

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.
