Watershed Moments

Lopatcong Creek

Lopatcong Creek pours down the Scotts Mountain Ridge in Harmony Township towards its appointment with the Delaware River twelve miles southwest at Phillipsburg.

The long view west to the Delaware Valley from Ragged Ridge

Hikers can explore the upper reaches of the Lopatcong along portions of the Warren Highlands Trail, crossing farms and rugged forest through the peaks and valleys of the watershed. From the access on Ridge Road, a woods road leads to a 1.8-mile ascent to a spectacular viewpoint at Ragged Ridge, also significant in Native American history as vantage point for signaling to other prominent ridges in the Delaware Valley. The trail diverges from the creek’s general path downhill as it points west towards the historic Van Nest-Hoff-Vanatta Farmstead on County Route 519. Reflecting three centuries of agricultural practices and rural architecture, the farmstead exemplifies the township’s heritage clearly expressed here and throughout the Lopatcong Valley. The trail then loops back towards the northwest edge of Merrill Creek Reservoir, crossing Lopatcong Creek near the Miller Farm access on Harmony Brass Castle Road.

The Van Nest Hoff-Vannatta Farmstead in Harmony

At the base of Scotts Mountain, Lopatcong Creek turns south through the valley, where Route 519 follows its alignment past the Warren County Farmers’ Fairgrounds. Generations of fairgoers have crossed the creek on the little wooden bridge at the entrance to the Warren County Farmers’ Fair. Over its long history the agricultural ambiance of the annual exposition has remained, while the excitement of tractor pulls, mud bogs, demolition derbies and carnival rides keep the attention of a wider audience. And for twenty-one years, the companion Hot Air Balloon Festival has brought growing awareness of the beauty of the Lopatcong Valley.

The Lopatcong watershed hosts the remnants of locks and planes at the western terminus of the Morris Canal, which are preserved and documented by the ever-expanding Morris Canal Greenway project. The creek drifts below State Route 57 and approaches the site where its waters once combined with the canal at the bottom of Plane 9 West at Port Warren, the longest of twenty-three inclined planes that conquered an unprecedented 1,674-foot change in elevation along the canal’s journey from Phillipsburg to the Hudson River at Jersey City. A visit to the Jim and Mary Lee Museum includes a walk around the property to see remnants of the inclined plane and a trip through the low tailrace tunnel into the chamber which contains a rare instance of the innovative turbine machinery that distinguished the Morris Canal from all others.

The creek continues west near the old canal bed that it once inhabited. Part of the Greenway, the towpath strides across the field through clumps of trees and the remains of a canal waste weir. West of Strykers Road the creek enters urbanity as it skirts a warehouse complex and ducks under Route 22 towards Lock Street in Phillipsburg. Always vital to the canal’s operation, the creek ran close, and sometimes joined this 1.2-mile stretch where another inclined plane and three locks lifted boats from the Delaware seventy-one feet in elevation from the Delaware River to the plateau of farmland to the east. Reserve an afternoon for a walk down Lock Street, which has been rerouted over the buried remnants of the canal. With the help of Greenway kiosks, and perhaps a live phone link to online documentation, you’ll notice the canal bridges, remains of Plane #10 West, and historic canal-era homes linked from past to present by the flow of the Pohatcong Creek.

Along Lock Street, the bottom of Plane 10 West meets Lopatcong Creek (above) across from an impressive stone home and springhouse built by early settler John Feit (below).

The commanding five-span stone arch Green’s Bridge towers over both the creek and South Main Street near the site of another historic canal lock. Just beyond, where the creek once again combined with the canal, another Greenway outpost documents more industrial heritage in a grassy area between the busy road and the creek. It covers the remains of the former Shimer Mill complex and mill pond that stored overflow from the creek to power other mills downstream. Beyond Millpond Park, Pohatcong Creek veers away from the canal trail and sneaks under railroad tracks into the Delaware.

Continue to explore Phillipsburg’s transportation heritage at the Port Delaware Canal Arch or take a ride on historic railroad equipment along the Delaware River Railroad Excursion to points south. Or rejoin the Warren Highlands Trail at the Northampton Street Bridge and follow North Main and River Road (Rt. 621) north out of town to the Marble Mountain Natural Resource Area. Near the top of Marble Mountain is the “ice cave,” actually the former Fulmer iron mine, with an intriguing array of ice stalagmites that form when the air is cold enough to freeze the dripping water inside. Four miles of trails through upland deciduous forest offer views across the Weygadt Gap to a Pennsylvania rock formation called St. Anthony’s Nose that towers over the opposite riverbank.

Morris Canal Greenway

The Morris Canal Greenway encompasses part of the historic canal’s alignment and is a cooperative effort to preserve and interpret canal sites to the public, and to offer recreational opportunities. Warren County has been an active partner in the effort to preserve this important part of transportation history, extending through the scenic Musconetcong, Pohatcong and Lopatcong valleys for thirty-three miles from Phillipsburg, on the west, to the county line near historic Waterloo Village on the east.

This section of the canal also contains Saxton Falls, where remnants of one of the canal’s 28 locks are visible.
