The Droitwich Canal is a synthesis of two canals in Worcestershire, England; the Droitwich Barge Canal and the Droitwich Junction Canal.
 The Barge Canal is a broad canal which opened in 1771 linking Droitwich Spa to the River Severn at Hawford Mill, Claines.
 The Droitwich Junction Canal is a narrow canal, opened in 1854, which linked Droitwich to the Worcester and Birmingham Canal.
 Both were built to carry salt, and were abandoned in 1939.
 They have been the subject of a restoration plan since 1973, and the Barge Canal was officially reopened in 2010, while the Junction Canal reopened in July 2011.
 Following the opening of the canal, ownership transferred to the newly created Canal and River Trust
The Canaveral Barge Canal provides an east-to-west link between the Atlantic Ocean and Indian River Lagoon across northern Merritt Island, Florida, in two segments separated by the Banana River.
 It is located 15 miles south of Titusville, Florida.
 The canal is 12 feet deep and has entrances to other water systems including Syke's Creek and various marinas.
 The canal links Port Canaveral along the Atlantic Ocean to the Intracoastal Waterway running down the center of the Indian River Lagoon.
 The canal was constructed to allow the transport of crude oil by barge to the two power plants south of Titusville, Florida.
A ship canal is a canal especially intended to accommodate ships used on the oceans, seas or lakes to which it is connected, as opposed to a barge canal intended to carry barges and other vessels specifically designed for river and/or canal navigation.
 Because of the constraints of accommodating vessels capable of navigating large bodies of open water, a ship canal typically offers deeper water and higher bridge clearances than a barge canal of similar vessel length and width constraints.
Schoharie Crossing State Historic Site, also known as Erie Canal National Historic Landmark, is a historic district that includes the ruins of the Erie Canal aqueduct over Schoharie Creek, and a 3.5 mi long part of the Erie Canal, in the towns of Glen and Florida within Montgomery County, New York.
 It was the first part of the old canal to be designated a National Historic Landmark, prior to the designation of the entire New York State Barge Canal as a NHL in 2017.
The New York State Canal System (formerly known as the New York State Barge Canal) is a successor to the Erie Canal and other canals within New York.
 Currently, the 525 mi system is composed of the Erie Canal, the Oswego Canal, the Cayuga–Seneca Canal, and the Champlain Canal.
 In 2014 the system was listed as a national historic district on the National Register of Historic Places in its entirety, and in 2016 it was designated a National Historic Landmark.
The office of Superintendent of Public Works was created by an 1876 amendment to the New York State Constitution.
 It abolished the canal commissioners and established that the Department of Public Works execute all laws relating to canal maintenance and navigation except for those functions performed by the New York State Engineer and Surveyor who continued to prepare maps, plans and estimates for canal construction and improvement.
 The Canal Board (now consisting of the Superintendent of Public Works, the State Engineer and Surveyor, and the Commissioners of the Canal Fund) continued to handle hiring of employees and other personnel matters.
 The Barge Canal Law of 1903 (Chapter 147) directed the Canal Board to oversee the enlargement of and improvements to the Erie Canal, the Champlain Canal and the Oswego Canal.
 In 1967, the Department of Public Works was merged with other departments into the new New York State Department of Transportation.
The Cross Florida Barge Canal, now officially the Marjorie Harris Carr Cross Florida Greenway is a protected green belt corridor, one mile (1.6 km) wide in most places.
 It is named for the leader of opposition to the Cross Florida Barge Canal, a canal project to connect the Gulf of Mexico and the Atlantic Ocean across Florida for barge traffic.
 Two sections were built but the project was cancelled, mainly for environmental reasons.
The Erie Canal is a canal in New York that is part of the east–west, cross-state route of the New York State Canal System (formerly known as the New York State Barge Canal).
 Originally, it ran 363 mi from Albany, on the Hudson River, to Buffalo, at Lake Erie.
 It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes.
 When completed in 1825, it was the second longest canal in the world (after the Grand Canal in China) and greatly affected the development and economy of New York, New York City, and the United States.
Erie Canal Lock 52 Complex is a national historic district located at Port Byron and Mentz in Cayuga County, New York.
 The district includes two contributing buildings (the Erie House and the blacksmith shop / mule barn); three contributing engineering structures (Erie Canal Lock 52, culvert, and canal prism of the enlarged Erie Canal); and archaeological sites associated with the canal operations.
 Lock 52 was constructed 1849-1853 as part of the Enlarged Erie Canal program.
 It remained in operation until the rerouting of the canal under the New York State Barge Canal System in 1917.
 The Erie House was built in 1894 and is a two story frame structure that housed a saloon and hotel.
Celilo Canal was a canal connecting two points of the Columbia River between the states of Oregon and Washington, U.S. just east of The Dalles.
