Parnall's Canal was a half mile long canal that was built in Cornwall in about 1720 near St Austell.
 It was closed due to a rock slide in about 1732.
 It was one of only five canals to be built in Cornwall, the others being the St. Columb Canal from Mawgan Porth to St. Columb, the Liskeard & Looe Union Canal, the Par Canal from Pontsmill to Par, and the Bude Canal.
The Hertford Union Canal or Duckett's Canal is a short stretch (c. 1.5 km) of canal in the London Borough of Tower Hamlets in East London.
 It connects the Regent's Canal to the Lee Navigation.
 It was opened in 1830 but quickly proved to be a commercial failure.
 It was acquired by the Regents Canal Company in 1857, and became part of the Grand Union Canal in 1927.
The Delta–Mendota Canal is a 117 mi aqueduct in central California, United States.
 It is part of the Central Valley Project and its purpose is to replace water in the San Joaquin River that is diverted into Madera Canal and Friant-Kern Canal at Friant Dam.
 Average annual throughput is 1993000 acre feet .
Pennsylvania Canal "(or sometimes Pennsylvania Canal system)" refers generally to a complex system of transportation infrastructure improvements including canals, dams, locks, tow paths, aqueducts, and viaducts.
 The Canal and Works were constructed and assembled over several decades beginning in 1824, the year of the first enabling act and budget items.
 It should be understood the "first use of any railway" in North America was the year 1826, so the newspapers and the Pennsylvania Assembly of 1824 applied the term then to the proposed Right of ways mainly for the canals of the Main Line of Public Works to be built across the southern part of Pennsylvania.
 Enacted before Railroads gestated during their infancy, the focus of the act was to create through building a canal system, the capability to ship heavy or bulk goods and connect Philadelphia to Pittsburgh—and "more importantly"—and "beyond" to the "new growth markets" in the developing territories reached by the Ohio River now called the midwest.
 Later, when updated in 1837 to reflect the experience of twelve years of toddler-railways, the term was also applied to railroads and new canals to be added to the state transportation system.
 As a crowning achievement, the Main Line of Public Works and the Pennsylvania Canal system topped 2100 ft in elevation by erecting the Allegheny Portage Railroad, which used a system of five inclines and five planes on each side of the Eastern Continental Divide at Cresson Pass in Cambria County to actually haul wheeled flat cars, which had halved canal boats placed on them, up and over the Allegheny Front and connect Pittsburgh to the Susquehanna.
 When finished in 1834 the trip from Philadelphia to Pittsburgh could be made in 3–5 days, weather conditions depending.
The Middlewich Branch of the Shropshire Union Canal is located in Cheshire, in the north west of England, and runs between Middlewich, where it joins the Trent and Mersey Canal, and Barbridge Junction, where it joins the main line of the Shropshire Union Canal.
 It is 10 mi long, and was planned as part of the Chester Canal, which was authorised in 1772, but the company ran out of money, and construction did not begin until 1827.
 The Trent and Mersey insisted that there should be no direct connection at Middlewich, and instead built the short Wardle Canal to join the two, charging large compensation tolls for traffic passing along it.
The Linlithgow Union Canal Society is a waterway society and a Scottish registered charity based at Linlithgow Canal Centre on the Union Canal at Linlithgow, West Lothian, Scotland.
 Also known as "LUCS", it was founded in 1975 by Melville Gray to "promote and encourage the restoration and use of the Union Canal, particularly in the vicinity of Linlithgow".
The Union Canal was a towpath canal that existed in southeastern Pennsylvania in the United States during the 19th century.
 First proposed in 1690 to connect Philadelphia with the Susquehanna River, it ran approximately 82 mi from Middletown on the Susquehanna below Harrisburg to Reading on the Schuylkill River.
The Grand Union Canal was a canal in England from Foxton, Leicestershire on the Leicestershire and Northamptonshire Union Canal to Norton Junction, close to Long Buckby Wharf on the Grand Junction Canal.
 It now forms the first 23 miles of the Leicester Section, a branch of the much bigger modern Grand Union Canal.
The Warwickshire ring is a connected series of canals forming a circuit around the West Midlands area of England.
 The ring is formed from the Coventry Canal, the Oxford Canal, the Grand Union Canal, the Stratford-upon-Avon Canal and the Birmingham and Fazeley Canal.
 It is a popular route with tourists due to its circular route and mixture of urban and rural landscapes.
The National Waterways Museum (NWM) is in Ellesmere Port, Cheshire, England, at the northern end of the Shropshire Union Canal where it meets the Manchester Ship Canal (grid reference [ SJ406771] ).
 The museum's collections and archives focus on the Britain's navigable inland waterways, including its rivers and canals, and include canal boats, traditional clothing, painted canal decorative ware and tools.
 It is one of several museums and attractions operated by the Canal & River Trust, the successor to The Waterways Trust.
