Summary
The earth dam, with a height of 30 feet and a length of 1000 feet, is situated on Cooper Branch and has a maximum storage capacity of 1040 acre-feet. The dam features an uncontrolled spillway and one outlet gate.
Owned privately, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes state inspections and enforcement. Although the hazard potential and condition assessment are not available, the dam is considered to have a moderate risk level. The last inspection was conducted in November 1983, indicating a need for updated assessments and risk management measures to ensure the safety and integrity of the structure.
With its scenic surface area of 70 acres, Miller Lake Dam provides a picturesque setting for recreational activities such as fishing, boating, and wildlife observation. As climate change impacts water resources, the dam's role in managing water levels and providing recreational opportunities becomes increasingly vital. Enthusiasts of water resources and climate management will find Miller Lake Dam an intriguing case study for understanding the intersection of conservation, recreation, and risk management in the face of changing environmental conditions.

Dam Data Reference
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.
