Green Turtle Pond Dam dam
Green Turtle Pond Dam
Green Turtle Pond Dam, located in West Milford Township, New Jersey, is a state-regulated structure with a primary purpose of recreation. The dam, made of earth and gravity, stands at a height of 35 feet and has a length of 305 feet, creating a reservoir with a normal storage capacity of 251 acre-feet. Situated on the Wanaque River-TR, the dam poses a high hazard potential but was assessed to be in fair condition as of August 2020.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Green Turtle Pond Dam undergoes regular state inspections and enforcement measures to ensure its safety and compliance with regulations. With a drainage area of 0.5 square miles and a surface area of 28 acres, the dam provides recreational opportunities for the surrounding community while also serving as a vital water resource in the region. Despite its high hazard potential, the dam's condition is monitored and maintained to mitigate risks and protect downstream areas.
Congressional District 05 in New Jersey, represented by Congressman Josh S. Gottheimer, oversees the jurisdiction of Green Turtle Pond Dam. The dam's emergency action plan (EAP) status and risk management measures are currently under review, reflecting ongoing efforts to enhance preparedness and safety protocols. As a key infrastructure asset in the area, Green Turtle Pond Dam plays a crucial role in water resource management and climate resilience initiatives, highlighting the importance of sustainable dam operations and maintenance practices.

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 Green Turtle Pond Dam
Where does the data for Green Turtle Pond 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 High 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.
