Summary
Completed in 1968 by the USDA NRCS, this earth dam stands at a height of 48 feet and has a length of 1405 feet, providing a normal storage capacity of 117 acre-feet and a maximum discharge of 2500 cubic feet per second. The dam is regulated by the Arkansas Natural Resources Commission and is under state jurisdiction for permitting, inspection, and enforcement.
Despite being rated with a low hazard potential, Cooper Creek Wid Site 3 is classified as having a moderate risk level, indicating potential challenges that need to be addressed. The dam currently holds a "Not Rated" condition assessment, with the last inspection conducted in June 2016. The structure features an uncontrolled spillway and outlet gates, with no associated locks. While the dam is not owned or funded by federal agencies, it serves a critical purpose in mitigating flood risks in the area, highlighting the importance of ongoing monitoring and maintenance to ensure its effectiveness in protecting the local community from potential disasters.

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.
