Summary

Built in 1919, this earth dam stands at a height of 33 feet and has a length of 380 feet, creating a reservoir with a storage capacity of 957 acre-feet. The dam is situated on Wolf Creek, a tributary that drains an area of 3.2 square miles.

With a spillway width of 224 feet and a maximum discharge capacity of 12,471 cubic feet per second, Wolf Creek Lake Dam is designed to handle significant inflows during periods of heavy rainfall. The dam underwent structural modifications in 1995 to enhance its safety and operational efficiency. Despite being classified as having a fair condition assessment, the dam is regularly inspected by the Texas Commission on Environmental Quality (TCEQ) to ensure compliance with state regulations.

Overall, Wolf Creek Lake Dam plays a critical role in managing water resources and mitigating flood risks in the region. With its picturesque surroundings and recreational opportunities, the dam serves as a popular destination for outdoor enthusiasts and visitors alike. Its strategic location and hydraulic functionality make it a vital asset for the local community and a source of pride for the state of Texas.

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.
