Summary

This reservoir has a storage capacity of 777 acre-feet and a normal storage level of 625 acre-feet, covering a surface area of 32.7 acres. Situated along the Stewart Creek-Tr river, this earth dam structure stands at a hydraulic height of 52 feet and a structural height of 59 feet, ensuring a steady flow of water for various purposes.

Managed by a private entity, the Franklin Treatment Plant reservoir is regulated by the North Carolina Department of Environmental Quality and the Dam Safety Program to meet state permitting, inspection, and enforcement requirements. Despite being classified as having a high hazard potential, the dam's condition assessment in 2020 rated it as fair. With a maximum discharge capacity of 175 cubic feet per second and a drainage area of 33 square miles, this reservoir plays a vital role in maintaining water security and supporting the local ecosystem in Mecklenburg County.

As climate change continues to impact water resources, the Franklin Treatment Plant reservoir serves as a critical infrastructure for managing water supply in the face of increasing challenges. With its strategic location and capacity to store and distribute water, this reservoir exemplifies the importance of sustainable water management practices in ensuring a resilient and secure water supply for future generations.

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.
