River Avon, Devon

The mouth of the River Avon, from Burgh Island

The River Avon, also known as the River Aune, is a river in Devon. It rises in the southern parts of Dartmoor in an area of bog to the west of Ryder's Hill. Close to where the river leaves Dartmoor a dam was built in 1957 to form the Avon reservoir.

After leaving the moor, the Avon passes through South Brent and then Avonwick and Aveton Gifford and flows into the sea at Bigbury on Sea.

The river is one of several named "Avon" in the British Isles. The name is from the British or Old Welsh language and just means "river" (Welsh: afon).
