Summary

Managed by the local government, this dam provides a storage capacity of 137 acre-feet, with a maximum discharge of 600 cubic feet per second. The dam has a surface area of 26 acres and a drainage area of 5 square miles, making it a vital resource for water supply and flood control in the region.

Despite its important role in water management, Asa Pond poses a high hazard potential due to its poor condition as assessed in October 2017. With a history of inadequate maintenance and the last inspection dating back to September 2014, there is a pressing need for improved risk management and emergency preparedness. The dam's spillway width of 37 feet and the nearby residential areas further emphasize the urgency of addressing its deteriorating state to ensure the safety of the community and the preservation of this valuable water resource.

As water resource and climate enthusiasts, it is crucial to advocate for the proper maintenance and rehabilitation of Asa Pond to mitigate the risks associated with its high hazard potential. Collaborating with the relevant state regulatory agencies such as the Department of Environmental Management, as well as local stakeholders, can help develop a comprehensive risk management plan and ensure that this recreational reservoir continues to serve its intended purposes effectively. By prioritizing the safety and sustainability of Asa Pond, we can safeguard its ecological importance and recreational value for future generations to enjoy.

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.
