Spooky Brook Dam Dam
Spooky Brook Dam
Spooky Brook Dam, located in Somerset, New Jersey, is a significant earth dam completed in 1971 for recreational purposes. With a height of 21 feet and a length of 300 feet, the dam has a storage capacity of 126 acre-feet and covers a surface area of 20 acres. It is situated along the Delaware-Raritan Canal, providing a serene backdrop for outdoor activities and water-related recreation.
Despite its recreational appeal, Spooky Brook Dam has been assessed as being in poor condition with a significant hazard potential. The last inspection in November 2019 highlighted the need for improvements to ensure its safety and stability. Managed by the local government, the dam falls under the regulatory oversight of the New Jersey Department of Environmental Protection (NJDEP), with state permitting, inspection, and enforcement in place to monitor its operations.
Given its historical significance and environmental impact, Spooky Brook Dam serves as a vital water resource in the region, supporting various aquatic ecosystems and recreational activities. As climate change continues to pose challenges to water management, there is a growing need for proactive measures to address the dam's structural integrity and ensure its long-term sustainability. Enthusiasts and stakeholders alike are encouraged to stay informed and engaged in the ongoing efforts to preserve and enhance this important infrastructure for future generations.

About Spooky Brook Dam
Where does the data for Spooky Brook 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 below 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.

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.
