Boonton Gorge

[2] Then the river drops over a small falls of about seven feet and flows under an arched stone walk-way bridge.

The water moves at a medium pace through this oval shaped pool before it starts its non-stop descent to the Jersey City Reservoir.

The river goes under a railroad bridge and then slows a little for about a hundred yards, when it drops over a three foot concrete USGS gauging station weir.

At this point the river drops forty feet in a quarter of a mile, when it finally empties into the Jersey City Reservoir.

Before the dam was built, the river dropped a total of two hundred sixty feet in a mile and a half.

At two points along the trails, near the falls, there are yellow "Riverphones" for calling emergency responders in the event of an accident.

[7] After 2011's Hurricane Irene, the righthand hiking trail (across the river from Main Street) eroded into a 85-ft drop.

[8] The New Jersey Fish and Game stock the river with rainbow and brown trout several times a year in the spring.

[10][11][12] Whitewater paddlers generally begin above the stone arch bridge and paddle down to the gauging station or the edge of the Jersey City Reservoir.

[7] There do not seem to be any verified reports of drownings involving canoeing, kayaking, tubing or rafting in Boonton Gorge since enthusiasts began running it in the 1970s.

[12][16] It has been reported that in the very early 1970s, 4 youths went down the gorge in tire tubes and 2 drowned as they were not wearing life vests [citation needed].
