Summary
Built in 1964, this Earth-type dam has a height of 19 feet and a storage capacity of 174 acre-feet. While primarily used for irrigation, the dam also serves recreational purposes, offering a surface area of 13 acres for outdoor activities. The dam is situated on the TR-South Sulphur River under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.
Despite its age, the Hefley Lake Dam remains structurally sound with a high hazard potential rating, indicating the importance of regular inspection and maintenance. The dam lacks a spillway and features one outlet gate for water release. While not federally owned or regulated, the dam is subject to state permitting and inspection requirements. The risk assessment for the dam is rated as high, emphasizing the need for proactive risk management measures to ensure the safety of the surrounding community and water supply.
In conclusion, the Hefley Lake Dam represents a vital piece of infrastructure in Texas, providing essential water resources for irrigation and recreation. As climate change continues to impact water availability and quality, dams like Hefley Lake play a crucial role in managing and distributing water resources effectively. With its strategic location and storage capacity, the dam serves as a key asset for water management in the region, highlighting the importance of ongoing monitoring and maintenance to safeguard against potential risks and ensure sustainable water resource management for the future.

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.
