Summary
The dam, primarily built for fish and wildlife conservation, stands at a height of 34 feet and spans a length of 1375 feet. With a storage capacity of 2640 acre-feet and a drainage area of 2.19 square miles, Patterson serves multiple purposes including irrigation and recreation. Despite being unregulated by the state and having a low hazard potential, the dam has a moderate risk assessment due to its proximity to the Seven Mile Creek.
Managed by the Natural Resources Conservation Service, Patterson features an uncontrolled spillway with a width of 240 feet. The dam's condition is currently not rated, and it has not undergone recent inspections. While the risk management measures and emergency action plans for Patterson are not specified, its moderate risk level suggests the need for further assessment and potential mitigation strategies. Overall, Patterson presents an interesting case study for water resource enthusiasts, especially those interested in the intersection of dam infrastructure, climate resilience, and wildlife conservation in the southeastern United States.

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.
