from the left, and about further on lies the derelict Sod House lock, the current head of navigation. Much of the canal beyond has been filled in, although drainage channels closely follow its route. There were two more locks, Mill lock and Holme Ings lock, and the canal terminated at Canal Head, about further on, and short of the town of Market Weighton. A short branch, the Holme Canal, turned off to the left immediately above Holme Ings lock, and remains in water. Above the junction with the River Foulness, the channel is heavily silted and navigation is difficult in all but the smallest boats.
