Everything I stated was related to water flowing downhill. Water flowing to a higher elevation requires either an input of energy (typically in the form of a pump; see the fleming hydro-ram as an example of moving a small volume of water up a gravitational gradient using the work of a large volume of flowing water) or a change in the local gravity gradient that makes "downhill" move toward higher elevations. In the first case it takes a huge amount of energy to move large volumes of water; in the second it takes exotic physics and/or magic.
