A short canal, nine and a half miles long, that was also part of the local drainage system. It gained its Act of Parliament in 1772 and opened in 1782, running from the River Humber but not actually reaching Market Weighton, finishing at a terminal basin about two miles south west of the town. The 3.5 miles (5.6 km) closest to Market Weighton was abandoned in 1900, but carrying from a brick works continued till 1950. The right of navigation through Weighton lock was lost in 1971.
