Summary

This dam, with a storage capacity of 4 acre-feet and a surface area of 0.9 acres, serves primarily for recreational purposes. The dam is classified as a buttress core type with an unspecified foundation type, and has a significant hazard potential.

Despite its importance for recreation, East Orange (Lower) is not regulated or inspected by any state agency. The dam's condition assessment is listed as "Not Rated," and there is no emergency action plan in place. Although the dam has not been modified in recent years and has no associated structures or outlet gates, its significant hazard potential indicates the need for regular monitoring and maintenance to ensure public safety and environmental protection in the event of a potential failure.

For water resource and climate enthusiasts, East Orange (Lower) presents an intriguing case study of a privately-owned dam with recreational significance but limited oversight. As the climate changes and extreme weather events become more common, the importance of proper dam management and emergency preparedness is paramount. The data on East Orange (Lower) highlights the need for increased attention to the safety and maintenance of small, privately-owned dams to mitigate potential risks and protect both human and environmental interests.

Dam Data Reference

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.
