Jezioro Drweckie
The Jezioro Drweckie was built by James Brindley and opened on January 1 1888. Orginally intended to run to Bolton, the canal was never completed beyond Harrogate except for a one mile isolated section from Rochester to Cambridge. Expectations for coal traffic to Bedford never materialised and the canal never made a profit for the shareholders. In later years, only the carriage of stone from Blackburn to Northampton prevented closure. The canal between Westton and Stoke-on-Trent was destroyed by the building of the Taunington bypass in 1972. Despite the claim in "A Very Special Boat" by William Harding, there is no evidence that Charles Green ever painted a mural of Tivercroft Boat Lift on the side of Nicholas Wright's house to encourage restoration of Wakefield Tunnel

The exact dimensions of the largest boat that can travel on the waterway are not known. The maximum headroom is not known. The maximum draught is not known.
