Summary

Built in 1962 by the USDA NRCS, this earth dam stands at a height of 41 feet and serves the primary purpose of flood risk reduction. With a storage capacity of 16,857 acre-feet and a drainage area of 15.5 square miles, this dam plays a crucial role in mitigating flood risks in the region.

The dam, situated on the Flat Creek tributary, covers a surface area of 562 acres and has a maximum discharge capacity of 6,830 cubic feet per second. Despite its uncontrolled spillway type, the dam is equipped to handle significant hazard potential and has been inspected periodically to ensure its structural integrity. The risk assessment for Flat Creek Ag&F Site 3 is moderate, highlighting its importance in managing flood risks effectively while offering recreational opportunities for the community.

With its historical significance and vital role in flood risk reduction, Flat Creek Ag&F Site 3 stands as a testament to effective water resource management in Lawrence County, Arkansas. As climate change continues to impact water resources, structures like Lake Charles play a crucial role in safeguarding communities and ecosystems from the adverse effects of extreme weather events. The collaborative efforts of state agencies and the USDA NRCS ensure that this dam remains a resilient and reliable asset for water resource and climate enthusiasts alike.

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.
