Deer Pond Dam dam
Deer Pond Dam
Deer Pond Dam, located in Boonton Township, Morris County, New Jersey, is a privately owned structure that serves primarily for recreational purposes. Built in 1930, this earth-type dam stands at a height of 17.3 feet and has a length of 395 feet, with a maximum storage capacity of 341 acre-feet. Situated on the Stony Brook, the dam has a low hazard potential and was last inspected in September 2020, with a satisfactory condition assessment.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Deer Pond Dam is state-regulated, permitted, inspected, and enforced. Despite its age, the dam continues to provide a surface area of 35 acres for recreational activities, with a normal storage capacity of 279 acre-feet. The surrounding area offers a picturesque location for outdoor enthusiasts to enjoy the beauty of nature while ensuring the safety and integrity of the dam through regular inspections and maintenance.
With its historical significance and contribution to the local community's recreational opportunities, Deer Pond Dam stands as a testament to the importance of water resource management and climate resilience. As climate change continues to impact water resources, the proper oversight and maintenance of structures like Deer Pond Dam are crucial to ensure the safety and sustainability of our water infrastructure for future generations.

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 Deer Pond Dam
Where does the data for Deer 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 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.
