Summary
Turner Reservoir Dam, also known as the Siler City Water Supply Lower Dam, is a vital water resource infrastructure located on the Rocky River in Chatham, North Carolina. Owned by the local government, this concrete gravity dam was completed in 2009 with a primary purpose of water supply. With a height of 12 feet and a hydraulic height of 9 feet, the dam has a storage capacity of 150 acre-feet, providing essential water resources to the region.
Regulated by the NCDEQ Dam Safety Program, the Charles L. Turner Reservoir Dam has a high hazard potential and is classified as being in fair condition as of the last assessment in 2017. The dam features state-of-the-art design and construction techniques to ensure the safety and reliability of the structure. With regular inspections and enforcement by regulatory agencies, the dam plays a crucial role in water management and supply for the community of Siler City and the surrounding areas along the Rocky River.
Overall, the Charles L. Turner Reservoir Dam is a key component of the water infrastructure in Chatham County, North Carolina. With its modern design, operational efficiency, and adherence to safety guidelines, the dam serves as a testament to effective water resource management in the region. For water resource and climate enthusiasts, this dam exemplifies the importance of sustainable water supply systems and the critical role dams play in ensuring water security for communities.

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.
