Summary
Designed by Cecil Bearden, this dam stands at a height of 25 feet with a stone core and soil foundation. With a storage capacity of 305 acre-feet and a surface area of 13.6 acres, Didier plays a crucial role in regulating the flow of water in the area.
Managed by the Oklahoma Water Resources Board, Didier is equipped with an uncontrolled spillway and has a low hazard potential. Despite being rated as in "Not Rated" condition, it is subject to regular inspections every 5 years to ensure its structural integrity and safety. The dam serves multiple purposes beyond flood control, making it a versatile and essential component of the local water resource infrastructure.
Although not rated for emergency preparedness, Didier poses a moderate risk level according to assessments. Its risk management measures and emergency action plan status are currently unknown, highlighting the importance of continued monitoring and maintenance to ensure the safety and reliability of this vital water resource structure in Oklahoma.

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.
