About this dam

Pompton Dam

Pompton Dam, located in Wayne Township, New Jersey, is a state-regulated concrete dam on the Ramapo River with a primary purpose of recreation. Standing at a height of 22.2 feet and stretching 1940 feet in length, the dam provides a storage capacity of 58 acre-feet and covers a surface area of 12 acres. The dam, completed in an unspecified year, serves as a crucial recreational spot in Passaic County, accommodating activities such as boating, fishing, and picnicking for local residents and tourists.

Despite its low hazard potential and fair condition assessment as of July 2012, Pompton Dam undergoes inspections every four years to ensure its structural integrity and safety. The dam is equipped with emergency action plans and contacts, although the specifics of their preparation and adherence to guidelines are not provided in the available data. With its role in flood control and water management on the Ramapo River, Pompton Dam contributes to the environmental and recreational landscape of the region, attracting visitors to enjoy its serene waters and picturesque surroundings.

Managed by the New Jersey Department of Environmental Protection (NJDEP), Pompton Dam stands as a testament to responsible water resource management and recreational infrastructure in the state. Its location in the Philadelphia District of the US Army Corps of Engineers and within Congressional District 11 of New Jersey underscores its significance as a vital component of the local water management system. As climate change impacts water resources, the maintenance and upkeep of dams like Pompton Dam become increasingly crucial in ensuring the sustainable utilization of water for recreational and environmental purposes in the face of changing climatic conditions.

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.

FAQ

About Pompton Dam

Where does the data for Pompton 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.
