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.
Cacapon River
From the county line, the river is bounded to its east by the George Washington National Forest and to its west by Baker Mountain (2024 feet/617 m). Throughout this stretch, the Cacapon River is also joined by sections of the old Winchester and Western Railroad grade. It continues its meandering course northeastward, flowing past the community of Intermont and Hebron Church. At Capon Lake, the river is joined by Capon Springs Run and is the site of the historic Capon Lake Whipple Truss Bridge. West Virginia Route 259 parallels the Cacapon River to its west along the eastern flank of Baker Mountain until the road turns east across the Kenneth Seldon Bridge at Yellow Spring. From Yellow Spring Gap, the river is fed by a run whose source is the "Yellow Spring".
