About this dam

Swimming River Reservoir Dam

Located in Red Bank, New Jersey, the Swimming River Reservoir Dam stands as a vital structure for water supply purposes, serving as a primary source for the surrounding area. Built in 1901, this earth dam towers at a height of 45 feet and stretches out to a length of 2400 feet, with a storage capacity of 14,300 acre-feet. The dam overlooks the Robins Swamp Brook and is regulated by the New Jersey Department of Environmental Protection, ensuring its safety and functionality.

With a high hazard potential but a satisfactory condition assessment, the Swimming River Reservoir Dam is regularly inspected every two years to maintain its integrity. The dam's emergency action plan was last revised in 2014, highlighting the importance of preparedness in case of potential risks or emergencies. Its location in Colts Neck Township within Monmouth County underscores its significance as a key component of the region's water infrastructure, providing essential services to local communities and ensuring a stable water supply for the area.

As a crucial piece of New Jersey's water resource management infrastructure, the Swimming River Reservoir Dam plays a pivotal role in regulating water flow, storage, and distribution. Its historical significance, coupled with its modern-day functionality, showcases the intersection of past engineering achievements and contemporary water resource management practices. Enthusiasts interested in water resources and climate will find the dam's specifications, operational details, and regulatory oversight to be of particular interest, highlighting the complex interplay between human-made structures and natural water systems in addressing societal needs and environmental stewardship.

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 Swimming River Reservoir Dam

Where does the data for Swimming River Reservoir 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.
