Summary

Standing at a height of 12 feet and stretching 720 feet in length, this dam holds a maximum storage capacity of 336 acre-feet with a normal storage level of 90 acre-feet. Despite not having a spillway, the dam features one outlet gate for controlled water release.

With a high hazard potential rating, the dam has not been rated for its condition assessment. While it is not regulated by the state, it is subject to state permitting and inspection requirements. The dam, situated on TR-Clear Creek, does not have associated structures and is not part of the US Army Corps of Engineers' jurisdiction. In the event of an emergency, contact information and emergency action plans have not been updated or prepared, highlighting potential risks associated with the dam.

Water resource and climate enthusiasts may find Live Oak Tank Dam intriguing for its historical significance in providing water supply to the region. The dam's design, construction, and maintenance reflect the importance of proper management of water resources in arid regions like Texas. As the dam continues to play a critical role in water storage and supply, ongoing monitoring and assessment of its condition and potential risks are essential to ensure the safety and resilience of the surrounding community and environment.

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.
