Summary

Completed in 1950, this earth dam stands at a height of 9.5 feet and spans 135 feet in length, with a maximum storage capacity of 345 acre-feet. The dam regulates the flow of Lawrence Brook and covers a surface area of 28 acres, supporting a drainage area of 15.2 square miles.

The dam is owned and regulated by the local government, with oversight from the New Jersey Department of Environmental Protection (NJDEP). Despite being classified as having a significant hazard potential, the dam is currently assessed to be in fair condition as of the last inspection in December 2019. The emergency action plan (EAP) for the dam was last revised in April 2020, ensuring that the necessary guidelines and measures are in place to address any potential risks or incidents.

Water resource and climate enthusiasts will find Davidsons Mill Pond Dam to be a key infrastructure for water management in Middlesex County. With its role in water supply and regulation, as well as its impact on the local ecosystem, the dam represents a critical link in the region's water infrastructure network. Ongoing inspections and maintenance efforts aim to ensure the safety and reliability of the dam for both its primary purpose and for mitigating potential risks associated with its operation.

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.
