Summary
Completed in 1959, this earth dam stands at a height of 45 feet and spans a length of 1025 feet, with a primary purpose of water supply. Situated on a tributary to the Canadian River, the dam has a maximum storage capacity of 1543 acre-feet and a normal storage capacity of 1125 acre-feet, covering a surface area of 62 acres.
With a high hazard potential and fair condition assessment, Cedar Lake Dam is regulated by the Oklahoma Water Resources Board and undergoes regular state inspections and enforcement to ensure its safety and functionality. The dam features an uncontrolled spillway and a single outlet gate for water management. In case of emergencies, an Emergency Action Plan (EAP) may be prepared to meet guidelines and ensure the safety of surrounding areas.
Water resource and climate enthusiasts will find Cedar Lake Dam to be an intriguing structure in Canadian County, Oklahoma, with its historical significance and role in providing water supply to the region. The dam's moderate risk assessment and state regulation highlight the importance of proper maintenance and monitoring to mitigate potential hazards and ensure the continued reliability of this essential infrastructure.

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.
