I believe the amount of water would depend on whether the wheel is an under
shot wheel or over shot.

With the overshot wheel the weight of the water in each of the buckets
moves the wheel, while the undershot wheel would depend on the current.


Overshot. Most of the ones I've seen only use about 200 gph for a 4ft wheel.
So 2000 gph might be a bit much for my little 3' wheel.
