Thank you for the input.
I was thinking more of a paddle boat wheel not the type for a mill.
would think you only would need force and volume of water not any
gravity drop,

Where do you think the force comes from ? Hint, it's gravity. Reduce the
'head' of water and you reduce the pressure / flow / power.
