Summary
Constructed in 1962 by the USDA NRCS, this earth dam stands at a height of 34 feet and spans 1476 feet along Flat Creek. With a normal storage capacity of 108 acre-feet and a maximum discharge of 1638 cubic feet per second, this dam plays a crucial role in managing water flow in the region.
Managed by the local government and regulated by the Arkansas Natural Resources Commission (ANRC), Flat Creek Wid Site 1 is classified as having a significant hazard potential. While its condition assessment is currently not rated, regular inspections ensure its structural integrity and operational efficiency. Despite its uncontrolled spillway and outlet gates, this dam continues to serve its primary purpose of flood risk reduction, safeguarding the surrounding area from potential water-related disasters.
With a risk assessment rating of moderate (3), Flat Creek Wid Site 1 remains a key component of water resource management in Lawrence County, Arkansas. While the dam's emergency action plan and risk management measures may need further development, its presence and functionality are essential in protecting the community from the impacts of extreme weather events and climate change. As water resource and climate enthusiasts, it is crucial to monitor and support the ongoing maintenance and management of this critical infrastructure to ensure the safety and resilience of the region.

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.
