Summary
This earth dam serves the primary purpose of flood risk reduction along the TR-Richland Creek, offering a storage capacity of 3024.77 acre-feet and a normal storage of 631.93 acre-feet. With a height of 27.2 feet and a length of 1700 feet, this dam plays a significant role in managing water resources and mitigating potential flood hazards in the area.
Managed by the Mississippi Department of Environmental Quality, Richland Creek WS Str 2a Dam has a high hazard potential but is currently assessed to be in satisfactory condition. The dam has uncontrolled spillways and outlets, making it essential for monitoring and inspection, which occurs every 5 years. While the risk assessment categorizes it as moderate, the dam's risk management measures and emergency action plan status are not specified. With its strategic location and design, this dam stands as a vital infrastructure for water resource management and climate resilience efforts in Rankin County.
As an integral part of flood risk reduction efforts in Mississippi, Richland Creek WS Str 2a Dam plays a crucial role in protecting the surrounding communities from potential inundation. With its earth construction and buttress core type, the dam reflects a balance between functionality and environmental considerations. Its association with the Natural Resources Conservation Service and compliance with state regulations demonstrate a commitment to sustainable water resource management. As water resource and climate enthusiasts, understanding the significance of structures like Richland Creek WS Str 2a Dam is essential for appreciating the complex interplay between infrastructure, natural systems, and community resilience.

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.
