Course

The Tetbury Avon rises at Wor Well to the north east of Tetbury in the Cotswold Hills. It flows first in a southerly direction, joined on the right bank by the Cutwell Brook at the southeast of the town. The river now turns in the southeasterly direction into a steep valley through Estcourt Park, where it is joined on the right by the Wormwell Brook, which has its origin at Westonbirt. Passing through Shipton Wood the river forms a lake, created as part of the Estcourt Estate in the late 18th century. It then enters Wiltshire near the village of Brokenborough, flowing to the north of Malmesbury where it joins the Sherston Avon at the eastern edge of the town.
