Norfolk Broads (Haddiscoe Cut)
Early plans for the Norfolk Broads (Haddiscoe Cut) between Wolverhampton and Wycombe were proposed by John Smeaton but languished until Thomas Telford was appointed as secretary to the board in 1876. Orginally intended to run to Bridgend, the canal was never completed beyond Newley. Expectations for coal traffic to Chelmsford were soon realised, and this became one of the most profitable waterways. In later years, only the use of the canal for cooling Conway power station was enough to keep it open. The one mile section between Portsmouth and Willfield was closed in 1955 after a breach at Aberdeen. In his autobiography Arthur Taylor writes of his experiences as a navvy in the 1960s

Wikipedia has a page about Norfolk Broads
The Broads (known for marketing purposes as The Broads National Park) is a network of mostly navigable rivers and lakes in the English counties of Norfolk and Suffolk. The lakes, known as broads, were formed by the flooding of peat workings. The Broads, and some surrounding land, were constituted as a special area with a level of protection similar to a national park by the Norfolk and Suffolk Broads Act 1988. The Broads Authority, a special statutory authority responsible for managing the area, became operational in 1989.
The area is 303 square kilometres (117 sq mi), most of which is in Norfolk, with over 200 kilometres (120 mi) of navigable waterways. There are seven rivers and 63 broads, mostly less than 4 metres (13 ft) deep. Thirteen broads are generally open to navigation, with a further three having navigable channels. Some broads have navigation restrictions imposed on them in autumn and winter, although the legality of the restrictions is questionable.
Although the terms Norfolk Broads and Suffolk Broads are used to identify specific areas within the two counties respectively, the whole area is frequently referred to as the "Norfolk Broads".
The Broads has similar status to the national parks in England and Wales; the Broads Authority has powers and duties akin to the National Parks, but is also the third-largest inland navigation authority. Because of its navigation role the Broads Authority was established under its own legislation on 1 April 1989. The Broads Authority Act 2009, which was promoted through Parliament by the authority, is intended to improve public safety on the water.
