Plodcast host Fergus Collins enjoys an autumn walk by the River Avon near Bath with Emma Brisdion of the Rivers Trust to take part in a Big River Watch. This citizen science project hopes to make an important difference to the health of Britain's polluted waterways. But it's also a chance to pause, watch the world go by and see what wildlife characters might turn up. Join them for a marvellously mellow adventure.
