Six Mile Run Reservoir Site Overview

Nestled in central New Jersey, Six Mile Run Reservoir Site, named for the stream that travels through the region, provides vital open space for enjoying the splendor of nature. The 3,037 acres of preserved land, once slated to be part of a reservoir, offers 13.5 miles on four marked trails that accommodate hiking, biking, birdwatching and horseback riding. Six Mile Run Reservoir Site has remained an oasis of farm fields and forests in an otherwise suburban landscape. Each trail has its own charm, allowing the visitor a chance to see an array of forest types, vast farm fields and beautiful views of Six Mile Run.

This area is administered by the Delaware and Raritan Canal State Park.

In the late 1950s, it was determined that additional water supply resources were needed for the state of New Jersey. The area around the Six Mile Run creek was identified as a possible location for such a site. In a process that took place over several years in the 1960s, properties were acquired by the state for the purpose of creating an additional water resource in central New Jersey. To that end in 1970, the area was put under the jurisdiction of the N.J. Department of Environmental Protection’s Division of Water Resources with the intent to develop it as a reservoir site. However, by 1993, alternative and adequate water sources had been identified and the Six Mile Run Reservoir project was shelved. No longer immediately needed, the administration of the newly-acquired properties at Six Mile Run was transferred to the Division of Parks and Forestry. The current trail systems through the former farmlands were soon created.

Today, Six Mile Run Reservoir Site provides an essential area to enjoy the outdoors with hiking, biking, horseback riding and hunting. The trail network provides visitors a glimpse into the region’s rich cultural history. The area was listed on the 1995 National Historic Register and is the largest agricultrual distric in New Jersey. Trail users can see the remains of 18th and 19th century farmhouses, Dutch-framed barns, windmills and silos that hint at the story of the early colonial settlers who inhabited the area in the 1700s, while they enjoy preserved open vistas of undeveloped land in the heart of central New Jersey.
