Summary

This earth dam stands at a height of 26 feet and spans a length of 283 feet along Tr-Ditch No. 1. With a storage capacity of 22 acre-feet, this structure serves the primary purpose of flood risk reduction, with additional functions including debris control.

Managed by the Natural Resources Conservation Service, Poinsett Site 105 has a low hazard potential and a moderate risk assessment rating. While the condition assessment is not available, regular inspections and maintenance are carried out by the NRCS to ensure the structure's integrity and functionality. Emergency action plans and inundation maps are yet to be prepared, but the structure meets guidelines for risk management.

Despite its relatively small surface area of 2 acres and limited drainage area, Poinsett Site 105 plays a crucial role in mitigating flood risks in the region. With its strategic location and design features, this structure stands as a testament to effective water resource management practices in the face of climate variability and increasing extreme weather events.

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.
