Summary
This structure serves primarily for flood risk reduction along the TR-Hell Creek river or stream. With a dam height of 27 feet and a storage capacity of 422 acre-feet, the dam plays a crucial role in managing water resources in the area.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, Hell Creek Watershed Structure Lt-9b-3 Dam is considered to have a low hazard potential and a moderate risk level. Despite not having a current condition assessment, the dam is still actively inspected, with state permitting, inspection, and enforcement in place to ensure its safety and functionality. The dam is equipped with an uncontrolled spillway and outlet gates, with a design that includes a buttress core and soil foundation.
For water resource and climate enthusiasts, Hell Creek Watershed Structure Lt-9b-3 Dam presents an intriguing case study in flood risk reduction and water management in Mississippi. With its historical significance and ongoing regulatory oversight, this structure serves as a beacon of sustainable infrastructure that balances the needs of water resource management with environmental protection. Its design and purpose showcase the importance of strategic planning and collaboration between federal, state, and local agencies to safeguard communities and ecosystems from the impacts of extreme weather 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.
