Although the condition assessment is listed as "Not Rated" and the hazard potential is considered "Undetermined," the dam is subject to state regulation, inspection, and enforcement, ensuring its safety and compliance with standards.
The dam, classified as an Earth type, is situated within the Wilmington District of the US Army Corps of Engineers. While specific details such as the year of completion, spillway type, and inspection frequency are not provided, the presence of state oversight and regulation indicates a commitment to maintaining the integrity and functionality of the structure. With a drainage area of 0.17 square miles, Lower Ayers Dam plays a crucial role in supporting agricultural activities in the region, highlighting the importance of water resource management and infrastructure upkeep in the face of changing climate patterns.
Despite certain information gaps regarding the dam's history and maintenance practices, Lower Ayers Dam remains a significant component of the water management system in Cumberland, Virginia.

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.
