Roman River
The Roman River rises from springs to the west of Great Tey. Three small streams merge, before the channel passes under the Great Tey to Little Tey road. It then passes under the railway line from to and another minor road, before reaching a major bridge under both the Great Eastern Main Line and the A12 road to the north of Copford. It turns to the south-east, to reach the B1022 road at Heckfordbridge. It is joined by a tributary flowing north-eastwards from Birch, and turns again to the east, passing under the B1026 Kings Ford Bridge to the north of Layer de la Haye. The channel widens to form the mill pond for Layer de la Haye watermill. On the south bank is Roman River Valley, a nature reserve, managed by the Essex Wildlife Trust.
