Summary
Built in 1995, this earth dam stands at a height of 16 feet and spans 330 feet in length, with a maximum storage capacity of 68 acre-feet. The dam also boasts a surface area of 7 acres and serves a drainage area of 0.14 square miles, making it a vital resource for the local community.
Managed by the Mississippi Department of Environmental Quality, Riley Pond Dam is state-regulated and inspected regularly to ensure its structural integrity and safety. With a low hazard potential and a moderate risk assessment rating, the dam provides valuable recreational opportunities while also mitigating potential flood risks in the area. While it may not have been rated for its condition, the dam continues to play a crucial role in water resource management and climate resilience efforts in the region.
Despite being a private-owned structure, Riley Pond Dam underscores the importance of collaboration between state agencies and local communities in managing water resources effectively. With its moderate risk assessment rating and low hazard potential, the dam stands as a testament to the successful partnership between regulatory agencies and private owners in ensuring the safety and sustainability of water infrastructure in Mississippi. For water resource and climate enthusiasts, Riley Pond Dam serves as a model for responsible dam management and the promotion of recreational activities in a sustainable manner.

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.
