Hi tjj, Yes I've seen various wells at Avebury shown on old maps and have of course seen the well in the Keiller Room in the Red Lion boozer. I can't say for sure if it ever dries up in the summer but I know that every time I go there (very often) it has always shown water which pleased me because of the research I was doing. My comment about whether they ever had to be deepend would have course been aimed at when they were in daily use. Not quite sure how low the water table at Avebury drops to in the summer but of course the Avebury Winterbourne stream nearly always runs dry doesn't it. And it would make sense I suppose if you were digging a new well in times gone by then the best time to dig it would be in the dry season so that when you did hit water at least you knew pretty well that you'd always get it after that. Incidentally, some years ago now I saw a guy digging an exploratory hole in a dry Winterbourne stream just down from the road opposite the car park. He was down about 3 feet when it started to moisten!
