Summary
This earth dam, with a height of 39.8 feet and a length of 1335 feet, serves to protect the surrounding area from potential flooding by the South Fork Ozan Creek. With a normal storage capacity of 170 acre-feet and a maximum discharge of 1116 cubic feet per second, the dam plays a critical role in managing water flow and reducing flood risks in the region.
Managed by local government authorities and regulated by the Arkansas Natural Resources Commission (ANRC), Ozan Creek SWCD Site 11 has a moderate risk rating and a low hazard potential. While the dam's condition assessment is not rated, it is subject to state inspections, enforcement, and permitting to ensure its continued safety and effectiveness. The structure features an uncontrolled spillway and outlet gates, highlighting its reliance on natural water flow mechanisms for flood management. With a focus on flood risk reduction as its primary purpose, this dam serves as a vital infrastructure asset in the region's water resource and climate resilience efforts.
Despite its low hazard potential, Ozan Creek SWCD Site 11 plays a crucial role in safeguarding the local community from potential flooding events. With its strategic location along the South Fork Ozan Creek and sophisticated design by the USDA NRCS, this earth dam stands as a testament to effective water resource management and climate adaptation practices. As state-regulated infrastructure, its maintenance and operation underscore the importance of proactive risk management measures in ensuring the safety and resilience of water systems in the face of changing climate conditions.

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.
