Summary

The dam, with a length of 620 feet, creates a surface area of 21.3 acres and has a maximum storage capacity of 230 acre-feet. The dam is classified as an Earth type dam and has a low hazard potential.

The dam is situated on Lagrue Bayou-TR River, in the Memphis District, and is owned privately. The dam's condition assessment is marked as "Not Rated", with no recent inspection date available. Despite not being state regulated or inspected, the dam serves as an important resource for recreation in the area and contributes to the overall water management system in the region.

For water resource and climate enthusiasts, Abernathy Reservoir Dam offers a fascinating insight into the intersection of human infrastructure and natural ecosystems. The dam not only provides recreational opportunities but also plays a role in managing water resources in the region. With its low hazard potential and unique location, the dam serves as a valuable asset in the local community, showcasing the delicate balance between human development and environmental conservation.

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.
