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.
Yellow River
According to the China Exploration and Research Society, the source of the Yellow River is at 34° 29' 31.1" N, 96° 20' 24.6" E in the Bayan Har Mountains near the eastern edge of the Yushu Tibetan Autonomous Prefecture. The source tributaries drain into Gyaring Lake and Ngoring Lake on the western edge of Golog Prefecture high in the Bayan Har Mountains of Qinghai. In the Zoige Basin along the boundary with Gansu, the Yellow River loops northwest and then northeast before turning south, creating the "Ordos Loop", and then flows generally eastward across the North China Plain to the Gulf of Bohai, draining a basin of which nourishes 140 million people with drinking water and irrigation.
