Summary

Built in 1961 by USDA NRCS, this earth dam stands at a height of 25 feet and has a storage capacity of 533 acre-feet. It is designed to control the flow of the TR- Glady Creek, a tributary of the larger Turkey Creek watershed, providing crucial protection against flooding in the region.

Managed by the local government and regulated by the Mississippi Department of Environmental Quality, the Y-20-39 Dam has a low hazard potential and a moderate risk assessment rating of 3. While it is currently deemed to be in "Not Rated" condition, regular inspections and enforcement measures are in place to ensure its safety and effectiveness. With its primary purpose being flood risk reduction, this dam plays a vital role in safeguarding the surrounding community from potential water-related disasters.

Despite its uncontrolled spillway and outlet gates, the Turkey Creek Watershed Structure Y-20-39 Dam remains a reliable flood protection asset for the residents of Spearman and the wider Yalobusha County. As part of the broader water resource management efforts in the area, this dam serves as a testament to the importance of sustainable infrastructure in mitigating the impacts of climate change and preserving the natural habitat of the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
