The gallery is split into 3 sections. This is not done by any official means whatsoever, but just as I feel it appropriate to get a ‘feel’ of the Severn estuary and to add some order to the photos  :

The upper estuary (from Gloucester to Lydney).  

The lower estuary (from Lydney to Clevedon).

The Bristol Channel (from Clevedon, seawards).
