Summary

This earth dam stands at a height of 31 feet and spans 346 feet in length, with a primary purpose of reducing flood risks along the Tr-Holly Springs Branch. Managed by the Natural Resources Conservation Service, the dam has a moderate risk assessment rating of 3, with a low hazard potential.

The dam has a storage capacity of 45 acre-feet, with a normal storage level of 13 acre-feet and a surface area of 2 acres. While the dam has uncontrolled spillways and outlet gates, it has not been modified since its completion. The structure is currently in a condition assessment status of "Not Available," with no inspection frequency specified. The risk management measures and emergency action plan for the dam are also not available, indicating a need for further assessment and planning to ensure the safety and functionality of the structure.

Overall, Poinsett Site 111 serves as a crucial infrastructure for flood risk reduction in the area, but lacks detailed information on its current condition and management procedures. This data underscores the importance of maintaining and monitoring water resource structures to protect communities and ecosystems from the impacts of extreme weather events and changing climate patterns. Enthusiasts of water resources and climate resilience will find opportunities for research and engagement in understanding the complexities of managing and safeguarding critical infrastructure like Poinsett Site 111.

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.
