Summary

Built in 1975 by HALFF AND ASSOCIATES INC, this earth dam stands at a height of 41 feet and spans a length of 1960 feet along Devils Creek. With a storage capacity of 1501 acre-feet, it serves as an important water resource for the region, supporting agriculture and recreational activities.

Managed by the Texas Commission on Environmental Quality (TCEQ), Lake Copper Breaks Dam features an uncontrolled spillway with a width of 200 feet. Despite being last inspected in 1997, the dam is deemed to have a moderate risk level. While its hazard potential and condition assessment are not available, the structure's operational status remains intact with uncontrolled outlet gates ensuring water flow management. Lake Copper Breaks Dam continues to play a crucial role in water resource management and climate resilience efforts in the area.

As part of the Fort Worth District, Lake Copper Breaks Dam is a vital component of the local infrastructure, with Mac Thornberry (R) as the representative for the congressional district. Although its specific surface area and drainage area are not listed, the dam's role in supporting irrigation and recreation activities cannot be understated. With its strategic location and design, Lake Copper Breaks Dam stands as a testament to the importance of sustainable water management practices in the face of changing climate patterns.

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.
