South Molton is a town and civil parish in the North Devon district, in the county of Devon, England. The town is on the River Mole. In 2021 it had a population of 6225.
The nearest watercourse on the river map is the River Mole, about 10 m from the middle of South Molton's gauges. It flows into the River Taw about 20 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Mole nearest the middle of South Molton's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
