Power Canal
A Power canal refers to a canal used for hydraulic power generation, rather than for transport of watercraft. The power canal was a major factor in the Industrial revolution in New England in the 19th century. Most early power canals were mill races used mechanically to transfer power directly from falling water to machinery in mill buildings. Later, the hydraulic power generated electricity locally for the same mill factories. These power canals were often filled in as electricity (transported by power lines) replaced the need for local water power, and road transport needs or city expansion needs reclaimed the land. Some hydraulic power canals were transformed into local electric generators, but most were closed. Remains of power canals can be seen in old mill towns and are often protected as historical structures today.

Lowell Power Canal System And Pawtucket Gatehouse
The Lowell Power Canal System is the largest power canal system in the United States, at 5.6 miles in length. It is operating through six major canals on two levels, controlled by numerous gates. The system was begun in the 1790s, beginning its life as a transportation canal called the Pawtucket Canal, which was constructed to get logs from New Hampshire down the Merrimack River to shipbuilding centers at Newburyport, Massachusetts, bypassing the 30-plus-foot drop of the Pawtucket Falls. In the early 1820s, Associates of the recently deceased Francis Cabot Lowell bought up the old Pawtucket Canal in what was then East Chelmsford, Massachusetts. Within a few years, the new industrial center that became Lowell was using canals feeding off of a widened and deepened Pawtucket Canal as a direct power source for their textile mills. The first of these canals was the Merrimack Canal, which powered the Merrimack Manufacturing Company. The repurposing of the Proprietors of Loc ...

Peters Cartridge Company
The Peters Cartridge Company was a company located along the Little Miami River in Kings Mills, Ohio, which specialized in gunpowder and ammunition production. Founded in 1887 by Gershom Moore Peters, the company supplied military ammunition to various countries during both world wars. Following its demise in 1944, the site was repurposed by Columbia Records and later Seagram, before being abandoned in 1968 and falling into disrepair. Its historic buildings, built in 1916, were added to the National Register of Historic Places in 1985.

Niagara Falls Hydraulic Power And Manufacturing Company
Niagara Falls Hydraulic Power & Manufacturing Company was an American company, based in Niagara Falls, New York that was the first company to generate hydroelectric power from Niagara Falls in 1882. The company built upon several predecessor companies efforts to construct a canal used for hydraulic mill power. In 1918, the company merged with Niagara Falls Power Company, which later became Niagara Mohawk and in 2002 was acquired by National Grid plc. Early history Porter, Barton and Company In 1805, " Porter, Barton & Company," which comprised Augustus Porter, Peter Porter, Benjamin Barton, and Joseph Anim, purchased the Niagara River and the American Falls from New York at a public auction.

Amoskeag Falls
The Amoskeag Falls are a set of waterfalls on the Merrimack River in Manchester, New Hampshire, United States. History "Amoskeag" derives from the Pennacook Native American word "Namoskeag", which roughly translates as "good fishing place". Here, the Merrimack River drops over the course of . Local tribes in the region fished Amoskeag Falls for its plentiful migrating sturgeon, alewife, and salmon, which were easily caught in the rapids. Natives typically used a combination of large nets strung across the river. Significant native settlements were sited near the falls, particularly on the high bluffs overlooking the east side of the river. In 1807, Samuel Blodgett started a canal and lock system at the river to help vessels navigate around the falls, opening the area to development. This soon led to the use of the falls for a power canal to provide water power for Manchester's 19th century industrial development, most notable for the Amoskeag Manufacturing Company.
