This is not something I'm planning to do, but the thought came to mind "can a living tree be used as a water feature"
The idea stems from the Walnut tree I posted photos of today in the "Whadya get up today" thread in reply #609 & #611

The rain was pouring and trickling down leaders into an old cavity between the convergence of several leaders. The result was water trickling out another old wound on the south side of the tree.
So... "what if"
What if a small pond or basin could be placed beneath the wound discharging water, to catch that water, and pump the water through a tube concealed behind the trunk, up into the upper cavity?
If the tree compartmentalized, and could prevent water from escaping elsewhere, do you suppose the water feature would have any effect on the tree?
Is is possible that it could help the tree by cutting-off air to the wound due to the puddle of water? (It does happen anyway, about 5 months of autumn and winter due to rain).
Any detrimental results? Here's the discharge wound ... see the other replies to see the image above the convergence of leaders ...
Has this ever been done before? I have not seen any such example with a big living tree. Stumps yes - live trees no.
