Summary
The reservoir, completed in 1955, has a dam height of 28 feet and a hydraulic height of 25 feet. With a storage capacity of 139 acre-feet, Cordell Reservoir primarily serves as a water source for the surrounding area, with a normal storage capacity of 124 acre-feet.
Situated on the West Boggy Creek, Cordell Reservoir is regulated by the Oklahoma Water Resources Board and undergoes regular inspections for safety and maintenance. The reservoir features a controlled spillway and an outlet gate for water management. Despite being classified as having a low hazard potential, Cordell Reservoir is considered to have a very high risk due to its location and potential impact in case of emergencies.
Overall, Cordell Reservoir plays a crucial role in providing water for the local community in Washita County, Oklahoma. With its earth dam structure and stone core, the reservoir ensures a stable and reliable water supply while being subject to rigorous regulatory oversight and safety measures to mitigate risks and ensure efficient operation.

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.
