Summary

Built in 1976, this structure stands at a height of 20 feet and has a storage capacity of 200 acre-feet, with a normal storage level of 75 acre-feet. The dam spans a length of 210 feet and has a controlled spillway with a width of 1 foot, ensuring efficient water release when necessary.

Managed by the Oklahoma Water Resources Board (OWRB), Gard is subject to state regulations and inspections, guaranteeing its structural integrity and operational safety. Despite being classified as having a low hazard potential, the risk assessment for Gard indicates a very high risk level, emphasizing the importance of continued monitoring and maintenance. With a history of regular inspections and a designated emergency action plan, Gard remains a vital component of the local water management infrastructure.

As enthusiasts of water resources and climate change, the data on Gard provides valuable insights into the intricate balance between water storage, dam safety, and environmental risk assessment. With its unique design features and operational parameters, Gard serves as a reminder of the critical role that infrastructure plays in ensuring water security and resilience in the face of changing climate conditions. As we continue to study and monitor water resources, structures like Gard offer a tangible example of the intersection between human engineering and natural resource management.

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.
