Summary
Built in 1947, this earth dam stands at 15 feet high and spans 55 feet in length, with a storage capacity of 311 acre-feet. Situated along the Warwick Creek, the dam serves as a vital component for managing water resources in the area, with a maximum discharge capacity of 481 cubic feet per second.
Despite its significant hazard potential, East Highland Lake Dam has been assessed as being in satisfactory condition, with regular inspections conducted by the New Jersey Department of Environmental Protection. The dam's emergency action plan was last revised in 2012, and while there are no current inundation maps or detailed risk assessments available, the structure is deemed to meet safety guidelines. With its lush surroundings and ample surface area of 27 acres, the dam continues to be a popular destination for outdoor enthusiasts and climate-conscious individuals alike.
As one of the key features in Sussex County, East Highland Lake Dam not only provides recreational opportunities but also plays a crucial role in water management and conservation efforts in the region. With its rich history dating back to the mid-20th century, the dam stands as a testament to the importance of sustainable infrastructure development and maintenance in the face of changing climate patterns. Its presence serves as a reminder of the delicate balance between human recreation and environmental stewardship, making it a focal point for water resource and climate enthusiasts seeking to understand the intersection of infrastructure and natural ecosystems.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
