Summary

Built in 1955, this earth dam stands at a height of 47 feet and stretches 1332 feet in length, creating a reservoir with a normal storage capacity of 258 acre-feet and a maximum storage of 978 acre-feet. The primary purpose of Lake Mullet Dam is to serve as a Fish and Wildlife Pond, providing essential habitat for various aquatic species in the region.

Despite its critical role in supporting local wildlife and providing irrigation water, Lake Mullet Dam is currently assessed as being in poor condition, with a moderate risk level assigned to it. The dam features an uncontrolled spillway and outlet gates, with a drainage area of 3.6 square miles and a maximum discharge capacity of 8951 cubic feet per second. The Texas Commission on Environmental Quality (TCEQ) regulates and inspects the dam to ensure its safety and compliance with state standards, although recent data updates and maintenance efforts are needed to address the dam's deteriorating condition.

For water resource and climate enthusiasts, Lake Mullet Dam offers a fascinating case study in dam management and environmental conservation. With its historical significance, unique design characteristics, and ecological importance, this structure presents opportunities for research, restoration, and collaborative efforts to safeguard its integrity and enhance its contribution to the local ecosystem. By raising awareness about the challenges facing Lake Mullet Dam and advocating for sustainable practices, stakeholders can work together to preserve this valuable water resource for future generations.

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.
