Summary

This private Earth dam stands at 57 feet in height and spans 1,280 feet in length, with a storage capacity of 6,270 acre-feet and a surface area of 165 acres. Situated along the Passaic River-OFFSTREAM, this dam is regulated by the New Jersey Department of Environmental Protection, ensuring state inspection, permitting, and enforcement measures are in place.

The dam's high hazard potential is mitigated by its satisfactory condition assessment as of March 2020, with emergency action plans in preparation to meet guidelines. Though the dam has not undergone recent modifications, its regular inspection schedule every two years helps maintain its structural integrity. The area's Congressional representative, Mikie Sherrill, falls under Congressional District 11, New Jersey, adding a political dimension to the dam's management and oversight.

Climate and water resource enthusiasts would find Canoe Brook Reservoir #3 Dam a significant infrastructure contributing to water supply management in the region. Its design, regulatory oversight, and emergency preparedness highlight the importance of sustainable water resource practices and the critical role dams play in securing water access for communities.

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.
