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 Flagami is a neighborhood in Miami, Florida, United States, roughly defined as south and east of the Tamiami Canal, north of the Tamiami Trail (US 41/South Eighth Street), and west of Red Road (SR 959/West 57th Avenue), bisected by Flagler Street.
Woodruff Block is a historic commercial building located at Oswego in Oswego County, New York.
 It is a four story masonry structure built about 1840 and modified between 1900 and 1930.
 It features rectangular cut stone columns with Doric capitals in the Greek Revival style.
 When built it was located strategically at the terminus of the 1828 Oswego Canal.
The Tamiami Canal or C-4 Canal, is a canal located in southern Florida in the United States.
 It flows in a west to east direction from the western part of the state in the Everglades past the Miami International Airport to a salinity control center near the Miami River.
 It averages 8 ft in depth and is over 100 ft wide in some areas.
The New York State Canal Corporation is responsible for the oversight, administration and maintenance of the New York State Canal System, which consists of the Erie Canal, Cayuga–Seneca Canal, Oswego Canal and Champlain Canal.
 It is also involved with the development and maintenance of the New York State Canalway Trail and with the general development and promotion of the Erie Canal Corridor as both a tourist attraction and a working waterway.
The Oswego Canal is a canal in the New York State Canal System located in New York, United States.
 Opened in 1828, it is 23.7 miles (38.1 km) in length, and connects the Erie Canal at Three Rivers (near Liverpool) to Lake Ontario at Oswego.
 The canal has a depth of 14 ft (4.2 m), with seven locks spanning the 118 ft (36 m) change in elevation.
The Junction Canal was a canal in the states of New York and Pennsylvania in the United States.
 The canal was also called the Arnot Canal, after the name of its principal stockholder, John Arnot of Elmira, New York.
 The canal was built and operated by a private stock company.
 The canal was partly open in 1854, but the entire length was not finished until 1858.
 The completed canal was 18 mi long and had 11 locks.
 Then intent was to lengthen the reach of the Chemung Canal deeper into Pennsylvania in order to connect to the canal systems there.
 Competition with railroads led to diminished use of the canal.
 In 1865 the canal was severely damaged by a flood.
 In 1866, the stock company was authorized to change its name to the "Junction Canal and Railroad Company," and work commenced in constructing a railroad on its right of way.
 The canal was last used in 1871, and was then abandoned.
The Runcorn and Weston Canal was a short canal near Runcorn in Cheshire, England, constructed to link the Weston Canal, which is part of the River Weaver Navigation, to the Bridgewater Canal and Runcorn Docks.
 It was completed in 1859, but was little used.
 Around half of it became the Arnold Dock in 1876, when it was made wider and deeper, and linked to Fenton Dock by a ship lock.
 The dock section and some of the remaining canal were filled in during the 1960s, and the remainder is in a derelict state.
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.
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.
