Forestport Dam on Black River and Sand Loader at Forestport, NY

Dam: (Satellite)

Street View, Jun 2025
[Note in the right background that NY-28 still has a truss bridge.]

This dam diverted water into a 10-mile feeder canal to the Black River Canal (BRC). The BRC, in turn, was a feeder canal for the Enlarged Erie Canal. Boonville was the summit of the BRC, thus this feeder canal joined the BRC in Boonville. That allowed 2/3 of the water to go south to the Erie Canal and 1/3 to go north to facilitate navigation on the BRC to Lyons Falls then on the Black River to Carthage.

The Black River must have a healthy, year-round flow because this is about the lightest flow I saw over the dam.

This feeder canal was navigable.

The canal goes off to the west including a large embankment that creates Alder Pond.

This shows how the feeder canal stayed above the elevation of Boonville while the Black River went lower in its valley.

This shows that the aqueduct is "wet."

Taking another look at a satellite image, one can see that it is wet.

Black River Canal Locks and 11.2mw?/5.6mw Powerhouse in Lyons Falls, NY

Powerhouse: (Satellite)

Black River Canal Overview

This is the waterfalls of Lyons Falls.
Evan Swingholm, Sep 2021

While looking for an image that still shows the paper mill, I found an image that allows us to clearly see the Black River Canal west of the river.
Google Earth, Apr 2005

Lyons Falls was the northern terminus of the Black River Canal. It used a series of locks to go around the falls.

This would be some of those locks.
LyonsFallsHistory

This is where the canal left the Black River upstream (south) of the waterfalls.

Before the locks, it appears the canal went through a cut next to the paper mill. The hydropower house is behind the white tower near the center of this photo.

Once you know where to look, the canal is easy to find along the river. The paper mill closed in 2001 [LyonsFallsHydro_history], and this is the last view that still has all of the paper mill buildings.
Google Earth, May 2013

Today, the only thing left is the power house.

The dam was built on top of the waterfalls to provide a larger hydraulic head for the mill.

The last update on their website was Aug 10, 2016. They got their FERC License Amendment, but the economy was "challenging." So I don't know if the $40m project was finished. Thus the question mark in the title: "11.2mw?/5.6mw." It appears that they did finish the site cleanup.

Black River Canal Aqueduct over Sugar River north of Boonville, NY

(Satellite, I don't know why Google Maps calls this Moose River.)

Black River Canal Overview

Cori Wilson posted five photos with the comment:
Sugar River Aqueduct of the Black River Canal, between Boonville and Port Leyden. 
  Not much here, there are some remains of the aqueduct on the north bank and a lot of fragments of its stone peppering the river bed.   Major difference between this and the Buck Hill Aqueduct is size, quality, and color of stone, almost surely the Sugar River quarry blocks. This was 200 feet in length when complete.

North of this river, traces of the canal was removed by the construction of NY-12 except for a rest park built next to four locks.
Google Earth, May 2013

This topo map confirms it was Sugar River that flowed into the Black River here.

Was there a town here? Or just a quarry?

Erie Canal Lock #46 in Syracuse, NY

(Satellite, the topo map below shows a lock was just west of Beech Street. Erie Blvd. was the canal.)

The Weighlock in Syracuse has been preserved and is now a museum.

Double locks on [at] Beech St. in Syracuse Ny
Steve Leyden: Surveyors did such a good job that the next lock to the east was in Frankfort, New York, 70 miles away.
[Since the lock in Frankfort was #45 [ErieCanal_locks], that would make this one #46.]
The longest distance between locks on the entire canal.
It was called 'The Long Level.' It shows how good the surveyors were.

This is the view from the southbound lanes. I included the sign on the left side of this view to help tie the views together.

1851-1922 Black River Canal Overview

GPS coordinates: AmericanCanalSociety_index

The Black River Canal was a 35 Mile canal that went from the Erie Canal in Rome to Lyons Falls. The lower part of the canal still functions as a feeder canal to the Barge Canal. The canal left Rome following the headwaters of the Mohawk River. The summit was in Boonesville. where it started following the Black River north. At Lyons Falls, boats could continue 42 miles on the Black River to reach Carthage. The Black River drains into Lake Ontario. It was authorized in 1836 as a navigable feeder canal because construction had begun on the Enlarged Erie Canal, and it needed more water. So the canal was used to divert water from the Black River to the Erie Canal. By 1851, boats were using the canal. The canal survived the 1877 abandonment of most lateral canals because of its importance as a feeder canal. Because the quarries that supplied material for the construction of the Delta Dam were north of Booneville, "the locks north of Boonville were refurbished once again in the hopes that the canal would be used up through the Black River and Carthage and the canal remained in a navigable condition into the 1920s. And yet, only eighty-four boats left Boonville for Rome in 1921, three in 1922, and none in 1923. The canal was un-officially abandoned by disuse." "An interesting footnote of BRC history was the close examination of the Morris Canal’s (New Jersey) inclined planes to replace the need for the great number of locks that were proposed along the canal. In all, the BRC was to use 109 locks over the thirty-five miles between Rome and Lyons Falls, which means about four locks per mile. In contrast, the Erie Canal used eighty-three locks along it’s 363 miles between Albany and Buffalo." (Delta Dam's reservoir engulfed Locks #7-#13.) Since the canal was abandoned after the railroads and roads in the area was built, many of the remnants are still visible compared to other 1800s canals. [AmericanCanalSociety]

"Built in the mid-19th century, the canal holds the record for the most locks along the shortest distance – 109 across 35 miles....The Forestport Feeder to Boonville was completed in 1848 after 10 years of construction, from which point it could be said that the headwaters of the Erie flowed from the Adirondacks. The first boat to climb the 70 locks and 693 feet from Rome arrived in Booneville in 1850. The rest of the canal, 386 feet down to Lyons Falls was completed in 1855. From there, barges were towed to and from Carthage along the Black River. Plans to extend the waterway to Lake Ontario or the St. Lawrence River never came to fruition." [AdirondakExplorer] (That is 3.1 locks per mile.)

"Timber, sawn lumber, and other wood products (pulp wood, firewood, shingles) were by far the most important commodities shipped on the canal, accounting for more than 90 per cent of the tonnage in the early years. In 1866, 29,000,000 board feet of lumber, 135,000 cubic feet of timber, and 10,000 cords of wood were shipped on the canal, destined primarily for Capital region, the Hudson Valley, and New York City." Farming developed on the cleared land, but farm products never generated the volume of freight that the timber industry provided. "Cheese and butter were shipped on the canal, as were wheat, rye, maize, and root vegetables. Over time, potatoes became the dominant export crop....The principal reason for the decline in canal business, however, was the fact that the region’s vast forests had been largely cleared. By 1892, when 2.8 million acres were set aside for the Adirondack Park , at least two-thirds of the area had been logged at least once. Timber--the mainstay of the canal--was no longer present in quantities large enough to sustain the canal as a viable enterprise. Although logging remained an important industry, the emphasis shifted to the local manufacture of furniture and paper products."


Several trails have been built along the canal.

The 10-mile feeder canal and the Black River Canal south of Boonville still has water because it now feeds water to the New York State Barge Canal. The water is diverted from the canal into Lansing Kill, which dumps into the Mohawk River. It appears the diversion is at Hidden Falls.

The canal is dry south of Hidden Falls, but I don't see much water in Lansing Kill.

The Lansing Kill River has carved an impressive gorge further downstream.
