Summary

The dam, standing at a height of 28.7 feet with a hydraulic height of 30.4 feet, serves as a key feature along the TR-South River, offering a surface area of 9.6 acres and a drainage area of 421 acres. Despite being categorized as an Earth dam with a Buttress core type, the hazard potential of Lake Charlotte Dam remains undetermined, with a moderate risk assessment score of 3.

With a maximum storage capacity of 380 acre-feet and a normal storage level of 131 acre-feet, the dam provides essential water resources for the surrounding area while also supporting outdoor recreational activities. While certain details such as inspection frequency and condition assessment are not rated or updated, the dam's uncontrolled spillway and outlet gates suggest a need for continued monitoring and risk management measures to ensure the safety and integrity of the structure. Overall, Lake Charlotte Dam stands as a vital component of the local water infrastructure, blending functionality with leisure in its contribution to the community.

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.
