Summary

The dam, made of stone with a soil foundation, stands at a height of 34 feet and has a structural height of 39 feet. It boasts a maximum storage capacity of 281 acre-feet and a surface area of 18.42 acres, serving as a vital resource for the local community's water needs.

Managed by the Oklahoma Water Resources Board (OWRB), Mccarty Pond Dam has a controlled spillway with a width of 25 feet and a maximum discharge of 667.7 cubic feet per second. Despite its low hazard potential and very high risk assessment rating, the dam's condition remains unrated. With a history of regular inspections every five years, this structure plays a crucial role in water resource management and climate adaptation efforts in Love County, Oklahoma.

As a key feature in the region's water supply infrastructure, Mccarty Pond Dam serves as a testament to the importance of sustainable water management practices. With its strategic location and functional design, this dam exemplifies the collaborative efforts between private owners and state agencies in maintaining critical water resources for the community. As climate change continues to impact water availability and quality, structures like Mccarty Pond Dam play a crucial role in securing reliable water sources for both current and future generations of residents in Love County.

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.
