The channel behind Mersea Island
Pyefleet Channel runs between the northern shore of Mersea Island and the adjoining Essex mainland marshes. It connects the shallow creeks and saltings towards the River Colne and lies well away from West Mersea's built-up waterfront.
Reeveshall and Maydays Marsh form part of this tidal landscape. Mud banks are exposed at low water, and there is no continuous promenade along the island's north shore.
Oyster fishing in the eighteenth century
The Colne oyster fishery's court minutes begin on 24 July 1758. They record its jurisdiction over the River Colne and creeks including Pyefleet and Bracelet or Bracefleet. The court appointed Isaac Decker as water serjeant and bailiff and recorded rules intended to prevent unauthorised dredging.
Pyefleet remained part of the regulated shellfish waters. Modern food-safety surveys identify Pyefleet Channel as a separate classification zone within the Colne shellfish production area.
Roman salt-making beside Maydays Farm
A scheduled Roman saltern lies on the saltmarsh about 750 metres north-west of Maydays Farm, beside Pyefleet Channel. Its surviving earthworks include a red mound, enclosing bank, ditch and a causeway leading towards the sea wall. The reddish soil is associated with fired clay and waste from salt production.
The northern side of the enclosure has been damaged by tidal erosion. The site is protected as a scheduled monument and is not a public attraction with managed access.
Historic records
The 1758 Colne fishery minutes name Pyefleet, while Historic England's saltern record documents the surviving Roman earthworks. See Mersea's red hills for other evidence of the salt industry.
Looking across Pyefleet from Mersea
The channel is most readily understood from the northern side of the island, where the land opens towards saltings and the mainland. Water covers and uncovers wide mudflats with the tide. The Roman saltern and the more remote marshes are protected or working landscapes; their mention in historical records is not a public-access invitation. Consult current public rights-of-way mapping before setting out on the north shore.
