Summary
This earth dam, with a height of 23 feet and length of 200 feet, serves primarily for recreational purposes, offering a surface area of 5.8 acres and a storage capacity of 68 acre-feet. The dam controls the flow of Mill Creek, providing a scenic backdrop for outdoor enthusiasts.
Despite being classified as having an "undetermined" hazard potential and a "moderate" risk assessment, the condition of Ainsworth Dam is currently not rated. While the dam does not have a controlled spillway, it is inspected, permitted, and regulated by the state of Mississippi. The dam's emergency action plan status, inundation maps, and risk management measures are not explicitly outlined in the available data, leaving some aspects of its safety and preparedness unaddressed.
For water resource and climate enthusiasts interested in Ainsworth Dam, its location in a picturesque setting and its role in providing recreational opportunities make it a noteworthy structure to study. As the dam continues to be monitored by state regulatory agencies, further assessments of its condition and risk management strategies may provide valuable insights into the intersection of water infrastructure, environmental stewardship, and public safety.

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.
