Summary

Owned privately, this earth dam stands at a height of 33.5 feet and spans a length of 1050 feet, creating a surface area of 6 acres and a storage capacity of 52 acre-feet. The dam is situated on the Pophandusing Brook-TR and is regulated by the New Jersey Department of Environmental Protection (NJDEP).

Despite its importance for recreation, Stiers Pond Dam poses a significant hazard potential due to its poor condition as assessed during the last inspection in November 2019. The dam has an inspection frequency of 2 years, indicating the need for regular monitoring and maintenance to ensure public safety. While the dam does not have a spillway, its primary purpose for recreation highlights the importance of maintaining its structural integrity and addressing any potential risks associated with its operation.

As a key feature in the White Township area, Stiers Pond Dam requires ongoing attention and potential risk management measures to mitigate its hazard potential and ensure the safety of surrounding communities. With its historical significance and recreational value, efforts to address its poor condition and enhance its resilience to climate impacts are essential for preserving this important water resource for future generations.

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.
