Port Isaac is a small fishing village on the Atlantic coast of north Cornwall, England, in the United Kingdom. The nearest towns are Wadebridge and Camelford, each ten miles (16 km) away. A nearby hamlet, Port Gaverne, is sometimes considered to be part of Port Isaac. The meaning of the village's Cornish name, Porthysek, is "port abounding in corn", indicating a trade in corn from the arable inland district.
The nearest watercourse on the river map is Port Isaac Stream, about 10 m from the middle of Port Isaac's gauges.
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 Port Isaac Stream nearest the middle of Port Isaac'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.
