Double Trouble North Dam dam
Double Trouble North Dam
Double Trouble North Dam in Ocean County, New Jersey, is a state-owned structure that plays a crucial role in flood risk reduction along the North Branch Forked River. This earth-type dam stands at 10 feet high and stretches for 1100 feet, with a storage capacity of 333 acre-feet. Despite its relatively low hazard potential, the dam is regularly inspected and maintained to ensure its fair condition and effectiveness in mitigating flooding events in the area.
Located in Berkeley Township, Double Trouble North Dam is under the regulatory oversight of the New Jersey Department of Environmental Protection (NJDEP). The dam's primary purpose is flood risk reduction, reflecting its role in protecting the surrounding community from potential water-related hazards. The dam's proximity to the Philadelphia District of the US Army Corps of Engineers highlights its importance in the regional water resource management infrastructure.
With a surface area of 50 acres and draining an area of 46.5 square miles, Double Trouble North Dam is a key component of the local watershed. Its fair condition and low hazard potential ensure that it continues to serve its purpose effectively. The dam's regular inspections, state regulation, and enforcement further underscore its critical role in maintaining water resource sustainability and climate resilience 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 Double Trouble North Dam
Where does the data for Double Trouble North 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 Low 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.
