The River Wye

High Wycombe takes part of its name from the river Wye, which now runs mostly underground through the town. Pann Mill corn watermill, at the eastern end of Wycombe, is the last remaining watermill on the River Wye. It was originally built in C12th.

The River Wye in Buckinghamshire is a river in England that rises in the Chiltern Hills of Buckinghamshire. It flows for around 9 miles (14 km), through High Wycombe on its way down to Bourne End, where it meets the River Thames on the reach above Cookham Lock.

It has a network of back-streams and tributaries, including the Hughenden Stream.

The River Wye is one of a number of important chalk streams in the Chilterns. 

Chalk streams are an internationally rare habitat and support a wide variety of wildlife, including some of the UK’s most endangered species. A chalk stream in good condition will have a gravel bed and crystal clear water. 

There will be good range of healthy native water and waterside plants and fish species. 

A healthy river environment will provide suitable habitats for birds such as the Kingfisher and Grey Wagtail.
