Summary
Completed in 1985, this dam stands at 19 feet in height and spans 1200 feet in length, with a storage capacity of 59 acre-feet. With a high hazard potential and moderate risk assessment rating, the dam is crucial for protecting the local community from potential flooding events.
Managed by the local government and regulated by the state of Arkansas, Poinsett Wid Site 118 plays a key role in flood risk reduction for the surrounding area, including the Ditch No. 1 - TR waterway. Despite being uncontrolled, the spillway and outlet gates help manage water discharge, with a maximum capacity of 774 cubic feet per second. Although the dam's condition is currently not rated and the last inspection was in 2014, its strategic location and design ensure it continues to serve its purpose effectively.
Water resource and climate enthusiasts will appreciate the engineering behind Poinsett Wid Site 118, as it showcases the importance of proper flood risk management in vulnerable areas. With a focus on protecting the community and surrounding environment, this earth dam stands as a testament to the collaborative efforts of the USDA NRCS, local government, and state regulatory agencies in safeguarding water resources and mitigating the impacts of extreme weather events in Poinsett County, Arkansas.

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.
