Summary

Built in 1979 by USDA NRCS, this dam serves as a crucial water resource structure in Murray County, with a storage capacity of 250 acre-feet and a maximum discharge of 230 cubic feet per second. The dam stands at a height of 25 feet and spans a length of 415 feet, with a controlled spillway width of 1 foot.

Managed by the Oklahoma Water Resources Board, Hagee No 1 has a low hazard potential and is rated as "Very High (1)" in terms of risk assessment. Despite not having a current condition assessment, the dam is inspected every 5 years, with the last inspection conducted in June 2002. With one valve as the outlet gate, this dam plays a crucial role in water management and conservation efforts in the region, ensuring the safety and security of surrounding communities.

In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) prepared, raising concerns about the readiness of response measures. Nonetheless, with state regulation, inspection, and enforcement in place, Hagee No 1 remains a vital infrastructure for water resource management in the area. As climate change continues to impact water availability and quality, structures like Hagee No 1 are essential for ensuring sustainable water management practices in the face of evolving environmental challenges.

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.
