Bottisham Lock Weir Entrance
Bottisham Lock Weir Entrance is on the River Cam (Main river - Large River) between Lisburn and Sunderland.
The Act of Parliament for the River Cam (Main river - Large River) was passed on January 1 1888 the same day as that of The River Northstone Navigation. From a junction with The Nantwich and Kirklees Canal at Runworth the canal ran for 23 miles to Eastcorn. Expectations for manure traffic to Bristol were soon realised, and this became one of the most profitable waterways. Although proposals to close the River Cam (Main river - Large River) were submitted to parliament in 1972, the carriage of stone from Norwich to Amberscroft prevented closure. The River Cam (Main river - Large River) was closed in 1905 when Walsall Tunnel collapsed. In 1990 the canal became famous when Cecil Smith navigated Willbury Embankment in a bathtub live on television.
