Therefore, although we have become accustomed to high seawalls in this corner of England they play an important role in providing respite from the serious threat of flood that is still ever present. Another signal of erosion are the many ancient Saxon fish traps that I come across that have slowly dissolved further away from the shoreline, mainly salt marsh, that once buffered the coast as a natural defense and has been completely washed away with just a few tell-tale fingers of mud pointing up for air. This brings us back to the idea of the original high water level inside rivers which would have meant they were far narrower than they are now and also gives some weight to one old legend that is: "from Mersea Island it was once possible to walk across to Sales Point, Bradwell at low tide". It also adds weight to a local ghost tale, that of a galloping horse charging across the mouth of the Blackwater, from Mersea Island, to then gallop down the Dengie coast on the seawall.
