The river mouth opening on the 08/12/2015 was an artificial opening and it was opened well North East of where it would have opened naturally; [at the lowest point of the berm]. The next 6 river mouth closures and natural openings all continued to happen 60 metres North East of past river mouth openings. The artificial opening at a high part of the berm had changed the location of the lowest part of the berm during subsquent river mouth closures. A consequence was the estuary water level remained slightly higher when the river mouth was open.
