Knowle is a village near Braunton located on the A361 road between Ilfracombe and Barnstaple in North Devon, England. It is in the civil parish of Braunton. Knowle is situated near to the Iron Age fortification of Knowle Hill Castle.
The nearest watercourse on the river map is the River Caen, about 10 m from the middle of Knowle's gauges. It flows into the River Taw about 7.5 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 Caen nearest the middle of Knowle'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.
Knowle is monitored by 1 Environment Agency river level station on the River Caen, in Devon. Water levels are updated every 15 minutes, providing real-time flood monitoring for the area.

No recorded flood outline is mapped around the Knowle town centre means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record. FloodRadar has separately logged 10 flood warnings or alerts for the Devon area since February 2026. See the flood history link below.
