Summary
Constructed in 1958 by the USDA NRCS, this dam serves primarily for flood risk reduction in the area. With a height of 22 feet and a storage capacity of 607 acre-feet, it is regulated by the Mississippi Department of Environmental Quality and falls under state jurisdiction for permitting, inspection, and enforcement.
Situated on Burkes Creek, this dam has a low hazard potential and is classified as not rated in terms of condition assessment. Despite its age, the dam remains in moderate risk with a risk assessment score of 3. While the dam's spillway is uncontrolled, its outlet gates also feature the same design. The structure has not been modified in recent years, and its emergency action plan status, as well as its inundation maps and risk management measures, are currently unknown.
Overall, Turkey Creek Watershed Structure Y-23-07 Dam plays a crucial role in managing flood risks in the region, with its earth construction and buttress core design. It stands as a testament to the importance of water resource infrastructure in safeguarding communities against natural disasters. Enthusiasts of water resources and climate science can appreciate the intricate details and regulatory oversight involved in the operation and maintenance of this vital piece of infrastructure.

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.
