Blackwater Estuary, Protected nature reserve and estuary in Essex, England.
The Blackwater Estuary spans 5,538 hectares between Maldon and West Mersea, featuring intertidal mudflats bordered by saltmarsh, shingle, and offshore islands.
Fish weirs from the Anglo-Saxon period remain visible in the estuary, where oysters have been continuously harvested for more than a thousand years.
The estuary maintains its role as a vital marine resource, supporting local fishing communities through aquaculture, commercial fishing, and shellfish collection activities.
Visitors can access information about the reserve by contacting Natural England at enquiries@naturalengland.org.uk or calling 0300 060 3900.
The radio ship Ross Revenge, former base of Radio Caroline, maintains its permanent mooring position within the waters of the Blackwater Estuary.
