Summary

This gravity dam stands at a height of 10 feet and stretches 480 feet in length, with a storage capacity of 190 acre-feet. The dam is situated on Bundicks Branch and is owned and operated by a private entity in the city of Woods Edge.

Despite not being regulated by the state, Goslee Mill Pond Dam is considered to have a significant hazard potential. The condition of the dam is currently listed as "Not Rated," with no recent inspection data available. While the dam does not have an Emergency Action Plan (EAP) in place, it is crucial for stakeholders to prioritize the safety and maintenance of this structure to prevent potential risks to the surrounding community and environment.

For water resource and climate enthusiasts, understanding the nuances of dams like Goslee Mill Pond Dam can shed light on the importance of proper maintenance and oversight of these structures. With its recreational purpose and significant hazard potential, this dam serves as a reminder of the critical role that infrastructure plays in managing water resources and mitigating risks associated with extreme weather events and climate change.

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.
