Summary

This reservoir falls under the ownership of the local government and is regulated by the NCDEQ Dam Safety Program, ensuring its compliance with state regulations. Completed in 2011, this Earth-type dam stands at a structural height of 42 feet with a hydraulic height of 37.5 feet, providing a normal storage capacity of 819 acre-feet and a maximum storage capacity of 917 acre-feet.

With a surface area of 32 acres and a drainage area matching its size, the Franklin Treatment Plant Raw Water Reservoir plays a pivotal role in managing water resources for the area. Its maximum discharge capacity of 383 cubic feet per second ensures efficient water distribution while its fair condition assessment and high hazard potential highlight the importance of regular inspections and maintenance. The reservoir's strategic location near Stewart Creek-Tr allows for optimal water sourcing and distribution, contributing to the overall water supply infrastructure in Mecklenburg County.

As a vital component of the water supply system in Charlotte, the Franklin Treatment Plant Raw Water Reservoir not only ensures a reliable water source for the community but also exemplifies the importance of sustainable water management practices in the face of climate change. With its capacity to store and distribute water efficiently, this reservoir serves as a testament to the efforts towards securing water resources for future generations. By adhering to state regulations and undergoing regular inspections, the reservoir continues to play a crucial role in water resource conservation and climate resilience in the region.

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.
