Lake Anne Dam dam
Lake Anne Dam
Located in Stillwater, New Jersey, Lake Anne Dam is a private Earth dam completed in 1950 primarily for recreational purposes along the Paulinskill River. Standing at 10 feet in height and spanning 260 feet in length, the dam has a storage capacity of 122 acre-feet and covers a surface area of 20 acres. With a maximum discharge rate of 110 cubic feet per second, the dam poses a low hazard potential and has been assessed to be in satisfactory condition as of the last inspection in October 2020.
Managed by the New Jersey Department of Environmental Protection (NJDEP) and regulated at the state level, Lake Anne Dam undergoes regular inspections every four years to ensure its structural integrity and safety. The dam's emergency action plan (EAP) was last revised in September 2008, and it meets established guidelines for risk management and emergency response. While the dam does not fall under the jurisdiction of the U.S. Army Corps of Engineers, its maintenance and operations are overseen by the private owners to ensure compliance with state regulations and enforcement.
With its picturesque location in Hampton Township, Lake Anne Dam provides a tranquil setting for outdoor activities and water recreation, offering a peaceful retreat for visitors to enjoy the natural beauty of Sussex County. The dam's role in providing recreational opportunities is underscored by its low hazard potential, which reflects the commitment to maintaining a safe environment for all who visit the surrounding area.

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 Lake Anne Dam
Where does the data for Lake Anne 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.
