Hackensack Res. # 2 (Weehawken) Dam dam
Hackensack Res. # 2 (Weehawken) Dam
Located in Weehawken Township, New Jersey, the Hackensack Reservoir #2 Dam is a privately owned structure that plays a crucial role in managing the flow of the Passaic River. This earth and gravity dam, with a length of 2850 feet, is regulated by the New Jersey Department of Environmental Protection and undergoes regular inspections to ensure its safety and integrity. With a high hazard potential and fair condition assessment, the dam poses a significant risk that requires careful monitoring and management.
Although the dam's primary purpose is not specified, its presence is essential for water resource management in the region. The dam's role in controlling the water flow, particularly during times of heavy rainfall or flooding, highlights its importance in safeguarding the surrounding areas from potential disasters. With the dam situated in a densely populated area in Hudson County, effective emergency preparedness plans and risk management measures are crucial to protect lives and property in the event of a breach or failure.
As a significant piece of infrastructure in the region, the Hackensack Reservoir #2 Dam serves as a critical component of the water resource and climate resilience efforts in New Jersey. With its strategic location along the Passaic River and its impact on the surrounding communities, the dam's maintenance and safety are paramount for ensuring the continued protection of the area against potential water-related hazards.

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 Hackensack Res. # 2 (Weehawken) Dam
Where does the data for Hackensack Res. # 2 (Weehawken) 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.
