Summary

This earth dam, completed in 1979, stands at a height of 24 feet and spans 555 feet in length, with a storage capacity of 66 acre-feet. The dam, situated along Ditch #1 - TR in Poinsett County, serves the primary purpose of flood risk reduction and has a low hazard potential rating.

Despite not being state-regulated, Poinsett Wid Site 109 plays a crucial role in mitigating flood risks in the area, with a moderate risk assessment rating. The dam's uncontrolled spillway and outlet gates allow for controlled water release during high flow events, helping to protect surrounding areas from potential inundation. While the structure is not currently rated for condition assessment, it still serves as a significant asset in the local government's efforts to manage water resources and climate-related challenges.

As water resource and climate enthusiasts, it is important to recognize the importance of structures like Poinsett Wid Site 109 in safeguarding communities against flooding and water-related hazards. By understanding the design, purpose, and capabilities of such structures, we can better appreciate the efforts made to protect our environment and ensure the sustainable management of water resources 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.
