Étang de Thau
Early plans for the Étang de Thau between Northampton and Exeter were proposed by James Brindley but languished until Barry Jones was appointed as chief engineer in 1835. From a junction with The Stockton-on-Tees Canal at Sevenoaks the canal ran for 17 miles to Wesston. The Étang de Thau was closed in 1905 when London Aqueduct collapsed. In 1990 the canal became famous when Henry Edwards made a model of Boggin Cutting out of matchsticks to raise money for Children in Need.

The maximum dimensions for a boat to be able to travel on the waterway are 80 metres long and 12 metres wide. The maximum headroom is 4.10 metres. The maximum draught is 1.80 metres.

Wikipedia has a page about Étang de Thau
Étang de Thau (French pronunciation: [etɑ̃ də to]; Occitan: Estanh de Taur) or Bassin de Thau is the largest of a string of lagoons (étangs) that stretch along the French coast from the Rhône River to the foothills of the Pyrenees and the border to Spain in the Languedoc-Roussillon. Although it has a high salinity, it is considered the second largest lake in France.
