Summary
5, is a local government-owned dam located in Whitfield, Mississippi. Built in 1985 by the USDA NRCS, this earth dam stands at a height of 29 feet and stretches 1925 feet in length. Its primary purpose is flood risk reduction along TR- Tumbaloo Creek, with a normal storage capacity of 215 acre-feet and a maximum discharge rate of 1727 cubic feet per second.
Managed by the Mississippi Department of Environmental Quality, Richland Creek Structure 5 Dam has a low hazard potential and is in satisfactory condition as of the last inspection in February 2016. The dam has an uncontrolled spillway and outlet gates, with no associated locks. The risk assessment for this structure is moderate, and it is subject to state regulation, permitting, inspection, and enforcement to ensure its continued safety and functionality in mitigating flood risks in the area.
Overall, Richland Creek Structure 5 Dam plays a crucial role in managing water resources and mitigating flood risks in Rankin County, Mississippi. With its strategic location and design, this dam serves as a vital infrastructure for local communities and environmental conservation efforts in the region. Its construction and maintenance reflect a collaborative effort between federal and state agencies to uphold water resource management standards and ensure public safety in the face of potential flood events.

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.
