millenium green downton wiltshire

Anybody know who has the fishing rights on the stretch of river at the millenium green in Downton?

I believe it's privately owned but the Association of Barbel Fishers are allowed to fish it for a small fee. Salisbury and District AC have the opposite bank (White Horse Stretch) and downstream (Charford). Downton AC have a small stretch upstream and the opposite bank at Charford (Lions).
