And while that might be a bit more on the overkill side of things, in plan 1 you can still capture twice. Now I'm not saying that capturing it just from the water wheel isn't a viable option, but I don't know what sort yields are possible from that, I'll have to look into it. And it just occurs to me that it may be possible to both pump the water AND capture the power from the turning of the wheel (course that might be pushing it as to what the rivers capable of doing).

Even a small yield of 50 watts equals 50 x 24hrs =1.2 kwhs. If you have no head available but you have a large enough stream / river, you would get more power from a tethered prop style hydro unit then you would yield from any pump/storage/hydro scheme. There is just too much loss from energy conversion to make a pump/storage/hydro setup worthwhile.
