River Yealm

The Yealm is a river in Devon in England that rises 1,411 feet 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 (submerged estuary formation) forms the waterfront to Newton Ferrers and Noss Mayo on its eastern side.

The harbour authority is made up of representatives from the civil parish councils of Wembury, Yealmpton, Brixton and "Newton and Noss".

It is the river and estuary between the River Plym which discharges at Plymouth and the River Erme which discharges by Meadowsfoot Beach, Mothecombe in Holbeton parish.

This short river once supported relatively large stocks of salmon, sea trout and brown trout but their populations have dwindled since the 1940s.

The River Yealm may have lost some of this stock of the most-eaten fish in the UK, but it has managed to retain other important species: it remains a key conservation area. The river acts as a bass hatchery. The Yealm is a Special Area of Conservation (SAC), and a Site of Special Scientific Interest (SSSI) chiefly for supporting many protected species.
