Route
From its source at Coalhill in South Hanningfield, the Rettendon Brook flows eastwards past Marks Farm, under the A130 road, to Rawlings Farm, then south of Pound Farm, east across Rettendon parish crossing the Saffron Trail.
The brook discharges into Fenn Creek near the roundabout at start/end of the A132 road, which is the normal tidal limit of the creek.[1] Fenn Creek is almost two miles long and flows south to the River Crouch of which it is a tributary.
The creek marks the western extent of the urban area of the town of South Woodham Ferrers. The Creek forms part of the Fenn Washland nature reserve.
