Summary

Completed in 1938, this earth and gravity dam stands at a height of 30 feet and has a length of 410 feet, with a storage capacity of 2120 acre-feet and a surface area of 170 acres. The dam spans the Stonehouse Brook and is regulated by the New Jersey Department of Environmental Protection.

Despite its age, Kakeout Dam has been assessed as being in satisfactory condition, with a high hazard potential due to its location and storage capacity. Regular inspections, with a frequency of every two years, ensure the dam's structural integrity and functionality. In case of emergencies, there are provisions for an Emergency Action Plan (EAP) although the last update was in 2018. The dam's risk management measures and potential inundation maps are areas that may need further attention to enhance the overall safety and security of the dam.

With its historical significance and crucial role in water supply management, Kakeout Dam serves as a vital piece of infrastructure in New Jersey. Its presence ensures the availability of water resources for the region while also highlighting the importance of maintaining and monitoring dams for the safety of surrounding communities and the environment. As climate change impacts water resources and infrastructure, ongoing assessments and updates to the dam's emergency preparedness plans will be essential to mitigate risks and ensure resilience in the face of changing conditions.

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.
