Foss Dyke
The Foss Dyke, or Fossdyke, connects the River Trent at Torksey to Lincoln, the county town of Lincolnshire, and may be the oldest canal in England that is still in use.
The canal is about 11 miles (18 km) long. It possibly follows an earlier line of the Trent, which emptied into the Wash prior to the end of the last Ice Age. Together with the 56-mile (90 km) Car Dyke it formed part an important transport route from Peterborough to York.
William Jessop was commissioned to survey the Witham and the Foss Dyke in 1791
