River Gipping
The source of the River Gipping is in the village of Mendlesham Green. It rises to the north of the village, just above the contour, and is fed by waters drained from fields. It heads towards the south-west, passing under the main street of Mendlesham Green by Green Farm, a grade II listed timber-framed and plastered farmhouse dating from the sixteenth and seventeenth centuries. It continues in the same general direction, passing Great Gipping Wood and Old Newton Hall, both on the north bank. The hall is a grade II* listed structure, dating from 1600 to 1630, with later additions. The joinery in one of the rooms in the left wing is exceptional. By Stonebridge Ford, the river is joined by a stream flowing northwards from Columbine Hall, a grade II* listed former manor house built of flint rubble around 1400, and another stream flowing southwards from Old Newton. By Bridge Farm, another timber-framed and plastered farmhouse dating from the late sixteenth century, Newton Bridge carries the B1113 road over the river, which then passes under a railway bridge, crosses the contour, and is joined by Haughley Watercourse, which flows southwards through Haughley and Dagworth.
River Gipping
After another crossing under the railway, the river skirts the eastern edge of Bramford and circles a hill, on top of which is Sproughton Manor, a grade II listed house built for Col Henry Phillipps in 1863 by the architect William Eden Nesfield. Sproughton Lock and mill are at the bottom of the hill. The mill is built in red brick and dates from the late eighteenth century. The mill race passes below the mill, which was operational until 1947, but all the machinery has been removed. Parts of the adjacent mill house date from around 1600. After passing under the A14 road, the river briefly heads north-east, through Chantry Cut, where Chantry Lock is situated, to pass under the railway. There are two bridges, as the railway line forks on the south side of the river. A flood barrier has been installed below the first bridge. Now passing through Ipswich, the river also forks, with the eastern branch being the River Gipping, and the western branch forming the start of the River Orwell. A modern sluice is located on the Orwell just below the junction. A final weir marks the position of Handford Sea Lock, below which the two channels rejoin. An outfall is situated below the junction, beyond which the river is tidal.
