Summary

Built in 1967, the earth dam stands at a height of 57 feet and has a storage capacity of 85,010 acre-feet. The dam's primary purpose is to provide water for the local community, with a normal storage level of 43,000 acre-feet and a maximum discharge capacity of 31,000 cubic feet per second.

Operated and regulated by the Texas Commission on Environmental Quality (TCEQ), Mud Creek Dam has undergone modifications in 1990 to enhance its structural integrity. The dam is equipped with an uncontrolled spillway, measuring 300 feet in width, and features outlet gates for water release. Despite being classified as having a "fair" condition assessment in 2017, the dam is considered to have a moderate risk level (3) according to the available data.

With its strategic location on Mud Creek and critical role in water supply management, Mud Creek Dam stands as a vital infrastructure asset for the local community. Its ongoing inspection and regulatory compliance ensure the safety and efficiency of water resource management in the region, making it an essential component for water resource and climate enthusiasts to monitor and appreciate.

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.
