Abbey River Tideway where there are two larger islands. It is much smaller than Canvey Island and the Isle of Sheppey and narrowly ahead of Andersey Island facing Abingdon-on-Thames, another market town with an abbey which had multiple medieval mills, another of note being Westminster Abbey, the island of which Thorney Island no longer exists. The outfall of the Abbey River is 400 m above Chertsey Bridge, into the weir pool of Chertsey Weir. The manmade strictly-considered "island" the bypass channel forms is outranked in size since the 2002 completion of the Jubilee River by the example containing Dorney and Eton, Berkshire.
Exe Estuary Exe Estuary The Exe estuary is an estuary on the south coast of Devon, England. The estuary starts just to the south () of the city of Exeter, and extends south for approximately eight miles to meet the English Channel (). The estuary is a ria and so is larger than would be the case given the size of the River Exe, the main river feeding into the estuary. On the east shore (from north to south) are the town of Topsham, the villages of Exton and Lympstone and at the estuary mouth, the seaside resort of Exmouth. Opposite Exmouth
