Colliford reservoir
Colliford reservoir on Bodmin Moor is an embankment construction which was completed in 1983.

The dam impounds water from the River St Neot to form a reservoir with a net storage of 28,540 megalitres and a surface area of 366 hectares.

Colliford supplies parts of North and South East Cornwall directly. It also makes releases to the River Fowey system which are abstracted and treated at Restormel and distributed throughout much of the rest of Cornwall.
