A most interesting design of weir that takes water at the Potato Wharf and links to the nearby River Medlock, which is at a lower level than the canal and actually passes beneath the whole basin complex. Originally water fed into the canal, but its quality deteriorated so drastically that a tunnel was constructed. Under flood conditions the water runs over this circular weir to enter the lower river close to where it surfaces.
