Powerville is the area located
around the Rockaway River’s
Powerville Dam. Although no
longer the industrial heart of
Boonton Township, several small
businesses still thrive here. The
industrial development of the area
goes back to the late 18th century
when foundries and slitting mills
were constructed to utilize the
black stone that the Indians had
been using to make axes. That
material is called magnetite or
iron ore.
By 1800 the area had begun to
grow. Conrad Hopler had not
only built a forge that was later
sold to Joseph Scott, but had also
constructed the first dam and
bridge across the Rockaway River
in Powerville. As a side note, it is
said that he was paid 3 bushels of
salt for construction of the bridge.
The bridge was built “towards the
close of the Revolution.” Shortly
after the war ended, he built the
dam across the river just above the
bridge. He owned not only the
forge, but also an extensive tannery.
In 1822, William Scott cut, at his
own expense, a high bank road
from the falls in Boonton to his
forge and grist mill in Powerville.
Today that road is referred to as
North Main Street. The construction
of North Main Street was not a
risk, but a calculated business
proposition. John Scott, William’s
brother who served as an Army
Captain in the War of 1812, was a
Commissioner and Director of the
newly formed Morris Canal and
Banking Company and was a driving
force behind it.
The later dam built by the Morris
Canal and Banking Company
flooded the area, creating a basin
where canal boats could anchor for
the night, load and unload, and
dock for repairs. During the summer
drought, this reservoir fed the
canal through Guard Lock #11.
The dam is constructed of concrete
over a wooden interior. To enable
mule drawn boats to cross the wide.
expanse of river a bridge had to
be constructed. One hundred seventy
years after it was built, the
center support stone pillar can still
be seen today in the middle of the
river thanks in large part to the
Historical Society of Boonton
Township’s stabilization project
completed in 1999.

The above photograph,
obtained from the New Jersey
Department of State Archives, is
looking up stream from the dam
and shows the basin, with the long
mule bridge leading to Lift Lock
#10. The white building (middle

residence and enduring Powerville
landmark.
There were three locks located in
Powerville, two of them were lift
locks used to raise and lower canal
boats. The current Boonton
Township firehouse on the corner
of Old Denville Road and Powerville
Road sits on top of Lift Lock
#9. Lift Lock #10 was located
just across Powerville Road between
the road and the river.
Traces of Guard Lock #11 where
the canal and river met can be
found at Griffith Park; here the
canal ran directly in front of the
Powerville Hotel which survives
today as a multifamily dwelling.
This landmark building on North
Main Street served as an inn and
way station for boatmen and excursionists,also catering to local
and transient trade. Nathan Hopkins,
proprietor of the hotel, was an abolitionist. His young teenage
son, Charles, transported m.any runaway slaves by horse and carriage through dark and dangerous rural tracks to the next stop along the Underground Railroad. Boonton Township is one of seventeen communities in New Jersey that are official sites on the Underground Railroad.
Iron master William Scott built, in
1826, the “William Scott Mansion”
which was the largest house in the
area at the time. This impressive Federal
manor house still stands today, on the
Merry Heart Nursing Home property.
The Scott family operated a forge and
saw mill at what is now Griffith Park
and had interests in several iron
mines as well. The original forge,
believed to have been constructed by
Conrad Hopler in 1794, was purchased
by Joseph Scott, William’s father, in 1802. William is credited with expanding the business and acquiring significant investments in land. Following William Scott’s death the forge was taken over by his son Elijah and Thomas C. Willis. (Willis was the son of the
Superintendent of iron works in old
Boonton. He built three houses on
North Main Street that still stand
today.) The forge was operated by
using charcoal produced from local
forests as its heat source.
