Summary
Managed by the local government, this earth-type dam on Pollys Creek holds a storage capacity of 4567 acre-feet and has a low hazard potential, making it a vital element in the region's water resource management system. State-regulated and permitted, the dam is inspected regularly to ensure its structural integrity and compliance with environmental standards.
Operated by the Mississippi Department of Environmental Quality, the Tuscumbia Watershed Structure 38 Dam plays a key role in protecting the surrounding area from flooding events. With an uncontrolled spillway and outlet gates, the dam is designed to manage the flow of water effectively during high-water events. Despite its moderate risk assessment rating, the dam has not been rated for its current condition, indicating a need for further evaluation to ensure its long-term functionality. Emergency action plans are yet to be prepared, highlighting the importance of proactive risk management measures for this critical infrastructure.
As part of the Memphis District, the Tuscumbia Watershed Structure 38 Dam serves as a vital component in the water resource infrastructure of Prentiss County, Mississippi. With its primary purpose of flood risk reduction, this dam plays a crucial role in safeguarding the community against potential disasters. As climate change continues to impact the frequency and intensity of extreme weather events, the proper maintenance and management of this dam are essential to ensure the safety and well-being of the local residents and environment.

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.
