Big Lebanon Lake Dam dam
Big Lebanon Lake Dam
Big Lebanon Lake Dam, located in Turnersville, New Jersey, stands as a significant earth dam completed in 1941 with a primary purpose of recreation. Situated along the Timber Creek South Branch, this dam boasts a height of 13 feet and a length of 260 feet, providing a storage capacity of 51 acre-feet and covering a surface area of 8 acres. Despite its historical significance, the dam's condition assessment is rated as poor, signaling a need for maintenance and improvements to ensure its continued safety and functionality.
Owned privately, Big Lebanon Lake Dam is regulated by the New Jersey Department of Environmental Protection, with state permitting, inspection, and enforcement processes in place. The dam's hazard potential is classified as significant, emphasizing the importance of proactive risk management measures and emergency action preparedness. With a designated inspection frequency of every two years, the dam's last assessment in April 2019 highlighted its deteriorating condition, calling for attention to prevent potential safety hazards and ensure the protection of the surrounding community and environment.
As a key feature of the Gloucester Township landscape, Big Lebanon Lake Dam serves as a recreational hub for locals and visitors alike. However, with its aging infrastructure and poor condition assessment, stakeholders must prioritize maintenance and rehabilitation efforts to uphold the dam's structural integrity and safety standards. With ongoing monitoring and compliance with regulatory guidelines, the future of Big Lebanon Lake Dam can be secured for generations to come, preserving its role as a vital water resource in the region.

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.
- 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.
- 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.
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, environmental 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.

About Big Lebanon Lake Dam
Where does the data for Big Lebanon Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
