Summary

Completed in 1979, this earth dam stands at 30 feet tall with a length of 1090 feet, providing a storage capacity of 497 acre-feet. The dam's primary purpose is flood risk reduction, with a spillway width of 100 feet and a maximum discharge of 2866 cubic feet per second.

Maintained by the local government and regulated by the TCEQ, Aquilla Hackberry Ck WS SCS Site 7 Dam has been inspected periodically, with the latest assessment in April 2021 rating its condition as fair. Despite its moderate risk level, the dam has not experienced any hazard potential as per available data. With a drainage area of 1.19 square miles and a normal storage capacity of 25 acre-feet, this structure plays a crucial role in managing water resources in Hill County, Texas, and contributes to the overall climate resilience of the region.

For water resource and climate enthusiasts, Aquilla Hackberry Ck WS SCS Site 7 Dam serves as a prime example of effective flood risk reduction infrastructure. Its strategic location, design features, and storage capacity demonstrate a proactive approach to managing water resources and mitigating potential hazards. As a key element in the local government's water management strategy, this dam plays a vital role in maintaining the safety and sustainability of the surrounding area, making it a noteworthy site for further study and appreciation in the realm of water resource management and climate adaptation.

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.
