Summary

Built in 1984 by the USDA NRCS, this dam serves as a flood risk reduction structure along the Tr-Big Creek. With a height of 23 feet and a length of 535 feet, the dam has a storage capacity of 64 acre-feet, making it a crucial asset in managing water resources and mitigating flood risks in the area.

Managed and maintained by the Natural Resources Conservation Service, Poinsett Site 114 has a low hazard potential and a moderate risk assessment rating. While the condition assessment is currently not available, the dam is designed to be uncontrolled, with an uncontrolled spillway width of 30 feet. Despite its relatively small surface area of 3 acres, the dam plays a significant role in protecting the surrounding community and infrastructure from potential flooding events, highlighting the importance of sustainable water resource management and climate resilience strategies in the region.

As an essential piece of infrastructure for flood risk reduction in Poinsett County, Poinsett Site 114 showcases the collaborative efforts between local government and federal agencies in safeguarding communities against water-related disasters. With its strategic location and design features, this earth dam stands as a testament to the ongoing commitment to addressing climate challenges and ensuring the safety and resilience of water resources in Arkansas.

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.
