Romney Island

Romney Island is an island in the River Thames in England connected to Romney Lock, at Windsor, Berkshire. It is a long thin island with trees and scrub, with the upstream end in Windsor and the downstream end almost at Black Potts.

The island has always been a popular place for angling and Isaak Walton used to fish from here. The island separates the weir stream from the navigation channel to the lock. Proposals to build a hydro scheme at the weir dated from 2004, with various revised schemes put forward since then. A revised scheme, using Archimedes screws, went ahead in 2011 and began generating power in 2013.
