WELCOME TO THE DELAWARE & RARITAN CANAL STATE PARK

With over 70 miles of linear multi-use path along an historic canal and additional trail networks and connections across several counties, park visitors have much to see, experience and explore here.  So take a look at our site then pack your hiking shoes, grab your mountain bike or strap that kayak to the car and plan a day trip to the D&R Canal State Park.

Dredge Project Updates for April 2019

Towpath Closures

The project is underway. Operations began in March 2018 and active dredging of the Canal and debris removal will resume in May 2019. Operations on the dewatering site, including trucking of the removed sediment, occur year-round. During periods of active dredging the portion of the Canal being dredged is closed to boaters. Occasional, temporary closures of the towpath may be necessary during the project. Signage will be posted at D&R Canal State Park entrances surrounding the closed areas to notify the public.

Project Updates

  • Work in the Canal will resume in May, with removal of aquatic vegetation scheduled to begin on May 1 and dredging to begin on May 6. This dredging season will continue through October 31, 2019.

  • As of May 1, the Canal will be closed to boaters between the Walking Bridge (near Little Valley Stables) and Griggstown Lock (“Reach 3” of the dredging project).

  • The next segment to be dredged in 2019 is Reach 5, which is between Griggstown Causeway and Blackwells Mills Causeway.

  • Dredged material will continue to be transported via floating pipeline to the material dewatering area located outside of the Canal and Park areas. Once dry, the material will be transported by truck to the American Cyanamid Site in Bridgewater, NJ for beneficial reuse. All material dredged in 2018 has been delivered to the site.

  • Three dredging seasons are expected (2018, 2019, and 2020). Final processing and transportation of dredged sediment will occur in early 2021.

TRAIL RESURFACING PROJECT IN MERCER COUNTY

Dredging Begins

A dredging project is planned for the D&R Canal from Kingston to Amwell Road at East Millstone.

This extensive and needed project (administered by NJ Water Supply Authority), began on July 9, 2018 and may take up to three years to complete. We thank you for your patience as the project continues along this section of the park.

Treating for Hydrilla

Hydrilla

Hydrilla was discovered in the Washington Crossing section of the Canal in July 2016. Hydrilla is an extremely aggressive invasive aquatic plant that spreads very rapidly and forms dense mats that can choke the flow of water through the canal. A lake management firm was hired in September, 2016 to survey, assess, and map the extent of hydrilla and other problem weeds in the high-priority segments of the Delaware & Raritan Canal. The survey report indicates that, for the 18.31 miles surveyed, submerged aquatic vegetation was collected at 96 percent of the sites, confirming the spatial extent and diversity of vegetation in the Canal. Hydrilla was observed at 56 percent of the survey sites.

On May 31, 2017, the Authority began a low-dose (<4 ppb) herbicide injection of Sonar Genesis for up to 120 days targeting the hydrilla and other nuisance aquatic vegetation. At these low rates, there are no restrictions on fish/fish consumption, human/animal water consumption or contact. There are some recommended water irrigation usage restrictions that have been posted along the tried areas of the canal. All Canal water customers have been engaged in the management planning process and continue to be updated on the status of treatment. The herbicide application is showing promising signs of effectively controlling the Hydrilla and other nuisance aquatic plants. The Authority and consulting firm are monitoring the status of plants and the herbicide concentrations at several points along the Canal.
