The island has a long history of cultivation
by man. Records exist of a bad flood in 1736 following which it was
drained, piled and enclosed by a sea wall .Following the protection the island was used
for cattle and sheep with additional uses from hunting the abundant
wild duck and catching eels which proliferated in the internal dykes.
A causeway was constructed from Stamford Farm
which allowed access to the island at low tide. The causeway was never
entirely dry although it was easily fordable.
During a bad flood in 1897 the sea wall was
breached and some livestock was drowned. Although some repairs were
carried out part of the island was lost to the river for ever.
Farming was supplemented by industry with the
island used for clay extraction and then the development of a brick and
tile works fed by a tramway linking the works to the quay on the
Riverside which was serviced by Thames Barges. Frederick
Bradbrook and James Bates worked the site in 1870 and then The
Bridgemarsh Brickfields Co. Limited worked the site from 1878 to 1882.
Problems with the location and the need to use a wash pan to separate
the clay from stones proved that this location was not viable and in
1892 the brickworks were abandoned.
Despite the warning no serious effort was made to maintain the seawalls which suffered further damage by floods in 1928.
The great floods of 1953 provided the final
nail for Bridgemarsh Island. The whole of the east coast suffered
serious flooding. The clay base at Bridgemarsh was used by servicemen
to fill sandbags that were used to protect other areas of the
coastline. Ironically Bridgemarsh itself was not protected from the
flood and surrendered to the sea.
Remnants of the old farmhouse and some
seawalls can still be seen at low tide. The island is now a haven for
wildlife and salt marsh flowers that can flourish without the attention
from man for the first time for hundreds of years.
