Summary
Built in 1942, this Earth-type dam stretches 1250 feet in length and reaches a height of 50 feet, with a storage capacity of 6696 acre-feet. Despite its age, the dam remains in fair condition, having undergone a structural modification in 1980 to ensure its continued functionality.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Mccarty Lake Dam serves as a crucial water resource for the region, with a normal storage capacity of 2600 acre-feet. The dam's spillway, an uncontrolled type with a width of 225 feet, helps manage water levels and prevent overflow during periods of heavy rainfall. While the dam poses a moderate risk level according to a risk assessment conducted, the emergency action plan and risk management measures are not currently available.
As an essential component of the water supply infrastructure, Mccarty Lake Dam plays a key role in ensuring water availability for the surrounding community. With its strategic location and effective operation, the dam continues to support water resource management efforts in the region, highlighting the importance of sustainable water infrastructure in addressing climate challenges and ensuring water security for future generations.

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.
