Summary
This local government-owned earth dam stands at a height of 39 feet and spans 800 feet along the Young Creek, serving primarily for flood risk reduction. With a storage capacity of 2,230 acre-feet and a surface area of 53.2 acres, the dam plays a crucial role in managing water resources in the region.
The dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure its structural integrity. Despite being classified with a high hazard potential, the dam is currently in fair condition according to the last assessment conducted in 2016. As a key infrastructure for flood risk reduction, the Ascalmore Structure Y-17a-02 Dam contributes to the overall water management efforts in the area, providing essential protection to the surrounding communities and supporting sustainable water resource practices.
With its strategic location in the Vicksburg District and association with the Natural Resources Conservation Service, the Ascalmore Structure Y-17a-02 Dam stands as a significant landmark in the region's water resource management. As climate enthusiasts and water resource advocates continue to monitor and assess the dam's condition, its importance in safeguarding against floods and ensuring water security for the local community remains a focal point of interest and concern.

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.
