Summary
Completed in 1943, this private-owned Earth dam spans 650 feet in length and reaches a height of 20 feet, providing a storage capacity of 620 acre-feet. The dam, situated on the TR-KELLY CREEK, serves as a vital component in the region's water infrastructure, ensuring a steady water supply for agricultural needs.
Despite its age, the Minor Lake Dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity and adherence to state regulations. The dam features an uncontrolled spillway with a width of 200 feet and two uncontrolled outlet gates. Its hazard potential is deemed as not available, with a moderate risk level assigned. While the dam's condition is not currently rated, its presence serves as a crucial resource for irrigation in the area.
For water resource and climate enthusiasts, the Minor Lake Dam represents a historical and functional landmark in the Texas water management landscape. With its primary purpose being irrigation, the dam plays a vital role in supporting agricultural activities in the region. As efforts continue to assess and manage the risk associated with the dam, its presence underscores the importance of sustainable water resource practices 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.
