Summary
Built in 1969 by the USDA NRCS, this earth dam stands at a height of 24 feet and has a storage capacity of 2500 acre-feet. Its primary purpose is flood risk reduction along the TR-Standing Pine Creek, making it an essential asset for water resource management in the area.
Managed by the Mississippi Department of Environmental Quality, this dam is regulated, permitted, inspected, and enforced by state authorities. Despite being classified as having a low hazard potential, its condition is assessed as fair, with a moderate risk rating. The dam features an uncontrolled spillway and outlet gates, allowing for the controlled release of water during times of excess flow. With a drainage area of 5.2 square miles, this structure plays a crucial role in mitigating flood risks and ensuring the safety of the surrounding community.
Standing Pine Watershed Structure 9 Dam serves as a key component of the flood control infrastructure in Leake County, Mississippi. With its buttress core and soil foundation, this dam has withstood the test of time since its completion over five decades ago. As climate change continues to impact the region, the importance of maintaining and monitoring this structure for future resilience and sustainability cannot be understated.

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.
