Summary

Built in 1968, this earth dam stands at a height of 12 feet and spans a length of 1040 feet, with a storage capacity of 430 acre-feet. Despite its small size, the dam plays a significant role in providing water for various purposes, including irrigation and domestic use, in the area.

Owned privately, Cuate Tank Dam is not regulated by the state but undergoes regular inspections to ensure its structural integrity. The dam, situated on TR-Clear Creek, has no spillway and features none outlet gates, adding to its unique design characteristics. While it poses a high risk (2) due to its size and capacity, the dam's condition remains unrated, highlighting the need for continued monitoring and maintenance to mitigate potential hazards.

For water resource and climate enthusiasts, Cuate Tank Dam offers a fascinating glimpse into the intersection of human engineering and environmental stewardship. As a vital water source in a semi-arid region like Texas, the dam's role in sustaining local ecosystems and communities underscores the importance of responsible water management practices. Despite its modest scale, Cuate Tank Dam stands as a testament to the ingenuity and foresight of those who recognize the value of safeguarding precious water resources 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.
