Summary
Built in 1970 by the USDA NRCS, this earth dam stands at a height of 35 feet and has a storage capacity of 683 acre-feet. It serves the primary purpose of flood risk reduction along the Ascalmore Creek, offering protection to the surrounding areas in times of heavy rainfall or storms.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, the Ascalmore Dam is classified as having a low hazard potential and a fair condition assessment as of March 2013. Despite its age, the dam continues to operate effectively, ensuring the safety and security of the residents in the city of Paynes. With a moderate risk assessment rating of 3, ongoing risk management measures are in place to address any potential issues and maintain the dam's integrity in the face of changing climate conditions.
Overall, the Ascalmore Structure Y-17a-76 Dam is a crucial piece of infrastructure in the region, playing a significant role in mitigating flood risks and protecting the local community from potential disasters. With its long-standing history and continued maintenance efforts, this dam stands as a testament to the importance of water resource management and climate resilience in the face of environmental challenges.

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.
