Summary
Managed by a private entity, this earth dam with a structural height of 58 feet and a length of 700 feet holds a storage capacity of 250 acre-feet. The dam's location in Camden County, near the city of Macks Creek, ensures a surface area of 28 acres and a drainage area of 153 square miles, providing essential water supply and recreational opportunities for the region.
Despite its significant role, Turner Lake Dam poses a high hazard potential, as indicated by its condition assessment of satisfactory but with a moderate risk rating. Regular inspections, with the last one conducted in November 2015, and a 5-year inspection frequency, ensure the dam's safety and functionality. With state regulation, permitting, inspection, and enforcement in place, the Dam and Reservoir Safety Program oversees the dam's operations, ensuring adherence to safety guidelines and mitigating any potential risks associated with its presence.
For water resource and climate enthusiasts, Turner Lake Dam presents a fascinating case study in balancing water management for irrigation and recreational use while maintaining the safety and integrity of a high-hazard structure. The dam's history, design features, and ongoing risk management efforts provide valuable insights into sustainable water resource practices and the importance of effective dam regulation and maintenance in ensuring the safety and resilience of water infrastructure in the face of changing climate conditions.

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.
