River Brit Sampling

Westcountry Rivers Trust monitors

The Westcountry Rivers Trust has a Citizen Science programme to monitor the state of the rivers in the South West.

As part of that effort Peter Little takes regular readings of the condition of the River Brit at the bottom of Bridge Street, Margaret Morgan-Grenville does the same at Oxbridge and Judith Lake reports on the state of Stoke Water, a tributary of the Brit, at a point just before they join by the site of the old Clenham Mill. They have been kind enough to share their readings with us which are laid out in the tables below.
