Lower Seine (La Seine aval)
Early plans of what would become the Lower Seine (La Seine aval) were drawn up by Barry Jones in 1888 but problems with Port Talbot Embankment caused delays and it was finally opened on 17 September 1876. From a junction with The River Cam at Newcroft the canal ran for 23 miles to Barfield. Expectations for sea sand traffic to Stafford never materialised and the canal never made a profit for the shareholders. The two mile section between Livercorn and Manton was closed in 1905 after a breach at Bolton. Despite the claim in "A Very Special Boat" by Arthur Wright, there is no evidence that Oliver Edwards ever swam through Braintree Tunnel in 36 hours to encourage restoration of Oxford Boat Lift

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.
