The Round Valley Reservoir Structures Refurbishment and Resource Preservation Project is making improvements to extend the operating life of the Round Valley reservoir.
The project is controlled and led by The New Jersey Water Supply Authority.
The Project will refurbish the reservoir structures with state-of-the-art design standards and construction techniques. The Project will extend the operating life of the Round Valley reservoir, which is the largest drinking water supply by volume in New Jersey.
The success of the Project will be vital to the State’s ability to sustain prolonged droughts by increasing this vital reservoir’s structural durability. This improved resilience will help ensure supplies of drinking water for future generations.
The New Jersey Water Supply Authority anticipates that major construction work will begin in 2018, with certain parts of the Project potentially beginning in 2017. Additional project timeline details will be announced as soon as the information is available.
Construction efforts are scheduled to minimize disruption to the public’s use and enjoyment of all that the Round Valley reservoir has to offer; however, certain disruptions may be unavoidable. The details of these activities will be announced as soon as the information is available.
It is possible that project efforts will require the lowering of the reservoir level, which could impact boaters and fishermen. The reservoir level may also be naturally lowered during drought conditions when more water is used, as occurred in 2016. The New Jersey Water Supply Authority adds water back into the reservoir by pumping when conditions permit. Whether additional, Project-related lowering will be necessary is yet to be determined. More information about reservoir levels, releases, and the current drought status, is available on the Authority's website.
There may also be temporary closures to park trails and local roads. All closures will be announced on the project website as soon as the information is available. Information will also be shared through local outreach efforts.

The Round Valley reservoir is connected to natural river systems, which enables water to be stored and moved around within the reservoir’s service area of central New Jersey. Balancing the needs of everyone that relies on this water is a critical part of the New Jersey Water Supply Authority’s work, especially given the drought that began in 2016. The reservoir provides a drinking water source for 1.8 million residents in central New Jersey and decisions to lower the water level are taken very seriously. With this in mind, the Authority is scheduling the Project in close coordination with the Division of Water Supply and Geoscience of the New Jersey Department of Environmental Protection.
Round Valley reservoir is part of a larger water supply system supply called the Raritan Basin system, which also includes the Spruce Run Reservoir. Additional information about the Raritan Basin system can be found on the Authority’s website.

A: The Round Valley boat launch is maintained by the NJ Department of Environmental Protection’s Division of Fish & Wildlife. The Authority has no additional information on the conditions at the boat launch. As reservoir water levels fluctuate, the Division of Fish & Wildlife makes efforts to accommodate boats.
