River Wey, Dorset - Definition and Overview

The River Wey is a short river in Dorset, south west England. The river springs from the South Dorset Downs, a ridge of chalk hills that separate Weymouth from Dorchester. Most of the river's course is in the Weymouth built-up area, running through the suburb Upwey, through Radipole Lake and into Weymouth harbour.

The river is important for wildlife and Radipole Lake is a National Nature Reserve run by the Royal Society for the Protection of Birds.
