Summary

Completed in 1996, this earth dam stands at 26 feet high with a hydraulic height of 25 feet and a length of 467 feet. It has a storage capacity of 23 acre-feet and serves an area with a drainage area of 115.2 square miles.

Despite being categorized as having a low hazard potential, Andy Mcdaniel Dam is considered to have a moderate risk level. The dam features an uncontrolled spillway with a width of 25 feet and has not been inspected since its completion in 1996. The condition assessment is listed as "Not Rated" with no emergency action plan (EAP) in place. The structure has no outlet gates and is not regulated or inspected by any state agency.

For water resource and climate enthusiasts, Andy Mcdaniel Dam offers an interesting case study in privately owned infrastructure designed for grade stabilization. With its unique characteristics, including a stone core and soil foundation, the dam provides valuable insights into earth dam construction and management practices. As an unregulated structure in a moderate risk category, it highlights the importance of monitoring and maintaining dams to ensure public safety and environmental protection.

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.
