Summary

This earth dam stands at a height of 31.4 feet, with a hydraulic height of 28.4 feet and a structural height of 37.4 feet. It has a storage capacity of 533.1 acre-feet and serves the primary purpose of flood risk reduction along the South Fork Ozan Creek.

The dam has a low hazard potential and is currently in a not rated condition as per the last inspection conducted in July 2015. While it is state regulated and permitted, with inspections and enforcement in place, its emergency action plan status and risk assessment suggest a moderate risk level (3). Despite the lack of a condition assessment date and other risk management measures, Ozan Creek SWCD Site 12 remains a critical infrastructure for managing water resources and protecting against floods in the region.

With its location in the Vicksburg District and under the jurisdiction of the ANRC, this dam plays a crucial role in water resource management in the area. Water resource and climate enthusiasts would find Ozan Creek SWCD Site 12 to be an essential piece of infrastructure in the battle against flooding and the preservation of the surrounding environment.

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.
