In the 1990s the two old sluices at this location on the Mill Avon at Tewkesbury were replaced by a single "fish belly sluice". When in the "up" position this forms a weir: when "down", during a flood, water can flow freely. The control room for the new sluice was mounted on legs above the footpath that crosses the Mill Avon at this point. My photograph was taken during moderate flooding in mid-January 2020.
