Summary
Constructed in 1970 by the USDA NRCS, this earth dam stands at a height of 42 feet and has a hydraulic height of 51 feet, with a structural height of 51 feet. It serves the primary purpose of flood risk reduction along Little Creek, with a storage capacity of 2360 acre-feet and a drainage area of 4.4 square miles.
With a low hazard potential and a moderate risk assessment rating, Cooper Creek Wid Site 5 plays a vital role in managing water resources in the region. The dam has not been rated for condition assessment, and the last inspection was conducted in June 2016. While the spillway type is uncontrolled and the outlet gates are also uncontrolled, the structure operates under state jurisdiction with permitting, inspection, and enforcement in place to ensure its functionality and safety.
Water resource and climate enthusiasts will appreciate the strategic design and purpose of Cooper Creek Wid Site 5 as an essential flood risk reduction measure in Lawrence County, Arkansas. The dam's location, storage capacity, and hydraulic features make it a key asset in managing water flow and protecting the surrounding areas from potential flooding events. With state regulation and oversight in place, this structure serves as a critical component of water resource management in the region, highlighting the importance of sustainable infrastructure for climate resilience.

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.
