Summary

With a height of 102 feet and a length of 675 feet, the dam has a storage capacity of 10,400 acre-feet and serves the West Milford Township area. The dam is regulated by the New Jersey Department of Environmental Protection (NJDEP) and undergoes regular inspections to ensure its fair condition and high hazard potential are managed effectively.

Despite its fair condition assessment, the Charlotteburg Dam remains a critical infrastructure for water resource management in the region. Its location along the Pequannock River and its significant storage capacity play a crucial role in supplying water to the surrounding communities. The dam's importance is further highlighted by its state jurisdiction, permitting, and inspection requirements, ensuring its safe operation and compliance with regulatory standards. Additionally, with a high hazard potential, the dam's emergency action plan and risk management measures are essential to mitigate potential risks and ensure public safety.

Congressional District 05's representative, Josh S. Gottheimer, oversees the Charlotteburg Dam, providing support for its operations and maintenance. The dam's historical significance, dating back to its construction in the 1960s, underscores its enduring role in water supply infrastructure. As climate change impacts water resources, the Charlotteburg Dam stands as a vital asset in managing water availability and ensuring the resilience of the local water supply system. Through ongoing monitoring, maintenance, and risk assessment, the dam continues to play a crucial role in safeguarding water resources and supporting the community's water needs.

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.
