The Yealm is a river in Devon in England that rises 430 m (1,410 ft) above sea level on the Stall Moor mires of south Dartmoor and travels 12 miles (19 km) to the sea, passing through Cornwood, Lee Mill and Yealmpton, a mid-sized village with a population of c.2,000 which is its largest settlement, before reaching its estuary which forms a ria bounded on its western side by Wembury. A deep inlet of this ria forms the waterfront to Newton Ferrers and Noss Mayo on its eastern side.
