Summary

Constructed in 1958 by the USDA NRCS, this dam stands at a height of 17 feet and has a storage capacity of 2140 acre-feet. Situated on the UNT of Tillatoba Creek, this structure plays a crucial role in managing water resources and protecting the surrounding areas from potential flooding events.

Managed by the local government and regulated by the Mississippi Department of Environmental Quality, Turkey Creek Watershed Structure Y-26-11 Dam is equipped with uncontrolled spillways and outlet gates. Despite being classified as having a low hazard potential, the dam is subject to moderate risk, highlighting the importance of ongoing monitoring and maintenance. With a drainage area of 1.66 square miles and a surface area of 40 acres, this dam plays a significant role in water resource management in the region.

As an essential piece of infrastructure in the Turkey Creek watershed, this dam serves as a critical tool in mitigating flood risks and ensuring the safety of local communities. With its historical significance and continued importance in water resource management, the Turkey Creek Watershed Structure Y-26-11 Dam stands as a testament to the ongoing efforts to balance environmental conservation with human development in the face of changing climate patterns.

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.
