 He identified a problem with the original plans, as the tide lock would not accessible except for a couple of days either side of spring tides.He therefore proposed creating a new cut from Rufford to Crossens, near Southport, crossing Martin Mere.This additional work would cost £2,530, but would have the advantage that the tidal range at Crossens would enable boats to reach the navigation more easily, the route would be shorter, and it would offer better flood protection the land above Rufford, as there would be two channels for flood water to reach the sea.
