A "Great Sluice" was constructed where the rivers joined, which included a navigable lock. Following flooding of the villages bordering the new route, a  channel was constructed from Newbridge near Thorne eastwards to Goole, where water levels in the River Ouse were between  lower than at Turnbridge. The channel was called the Dutch River, and was not intended to be navigable, so boats continued to use the lock at Turnbridge, until the sluice at Goole was swept away by floods in 1688.
