Summary
Built in 1960 for recreational purposes, the dam stands at a height of 19 feet with a hydraulic height of 16 feet. With a storage capacity of 127 acre-feet and a surface area of 12 acres, Abernathy Dam plays a vital role in providing recreational opportunities for the surrounding area.
Managed by the Natural Resources Conservation Service, Abernathy Dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. The dam has not been modified over the years and is equipped with uncontrolled spillways and outlet gates. Despite its moderate risk assessment, Abernathy Dam remains valuable for water resource and climate enthusiasts interested in the management and conservation of water bodies in the region.
Although not regulated by the state, Abernathy Dam undergoes regular inspections, with the last one conducted in June 2018. While it does not have an Emergency Action Plan (EAP) in place, the dam meets guidelines for risk assessment and management measures. As a significant structure in the area, Abernathy Dam serves as a reminder of the importance of sustainable water resource management and the need for proactive measures to ensure the safety and longevity of such infrastructure in the face of changing climate conditions.

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.
