Summary
Designed by USDA NRCS and completed in 1960, this earth dam serves a primary purpose of flood risk reduction in the area. With a dam height of 21 feet and a storage capacity of 242 acre-feet, the dam plays a crucial role in managing water levels and protecting the surrounding community from potential flooding events.
Managed and regulated by the Mississippi Department of Environmental Quality, the dam is classified as having a low hazard potential and a moderate risk assessment rating of 3. Although not currently rated for condition assessment, the dam's construction and design follow standards set by the Natural Resources Conservation Service. Despite being uncontrolled, the spillway type and outlet gates of the dam ensure effective water discharge during high-flow events, further enhancing its flood protection capabilities.
The Turkey Creek Watershed Structure Y-20-57 Dam stands as a vital piece of infrastructure in the region, safeguarding against flood risks and providing essential water resource management. As climate change continues to impact weather patterns, structures like this play a crucial role in protecting communities and ecosystems from the growing threats of extreme weather events. With proper maintenance and oversight, this dam will continue to serve its purpose effectively for years to come, highlighting the importance of sustainable water resource management in the face of a changing climate.

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.
