Summary
Standing at a height of 25 feet, this earth dam provides a storage capacity of 67 acre-feet, with a normal storage of 42 acre-feet and a surface area of 5 acres. Despite being privately owned and not regulated by the state, the dam poses a low hazard potential, with a condition assessment that is currently not rated.
This dam serves primarily for recreational purposes and is categorized as an earth dam with a buttress core type. Although details about its construction year and spillway type are not specified, Hicks Lake Dam South-Sec 20 remains an important structure in the area. As it is not under the jurisdiction of state agencies for permitting, inspection, or enforcement, it is essential for the private owners to ensure regular maintenance and upkeep to prevent any potential risks associated with the dam.
With an emergency action plan status that is unspecified and no recent inspection date provided, it is crucial for the owners of Hicks Lake Dam South-Sec 20 to prioritize safety measures and stay prepared for any potential emergencies. As the dam is not owned or funded by federal agencies, the responsibility falls on the private owners to maintain the structure's integrity and ensure the safety of both the dam and the surrounding community.

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.
