Quit screwing around wasting water and get back to work finishing that stream!
A undershot wheel is more efficient because the bottom of the wheel is going
in the same direction as the water in the stream, that is what my research has
shown when I was looking for ideas on wheel design.
The stream is my wife’s responsibility, she volunteered. 
Well, I’ve just learned something - I always had the overshot image in my head too.
Great build, thanks for posting Mark. Looking forward to the final installation.

I’ve only seen undershot wheels having the current being in a channel beneath the wheel.
But heck this makes sense, using the backside blades like that.
