Pequannoc Spillway

[1][2] The Pequannoc Spillway is an early 20th-century concrete spillway over 270 feet wide, equal in girth to the Great Falls of Paterson located along the Pompton River a quarter-mile south of the Pompton dam and associated guard bank in Pequannock Township's Aquatic Park.

Like its sister structure the Pompton Dam, the Pequannoc Spillway was originally made entirely of timber.

Constructed in the early 19th century the Pequannoc Spillway aided in navigation upriver along the Morris Canal during its almost 100 years of use.

On Vermeule's suggestion, the State of New Jersey has upgraded the dam to a concrete structure providing the same operation as it had previously performed.

However, unlike the Pompton Dam, the Pequannoc Spillway still allows water-flow over the entirety of its girth so claims of flood hazard have gained little traction.
