Yup.
If the river flows fast enough, a whater-wheel can be (and often is)
used, with some buckets attached in a smart way, using simple lever
principles to use the running-water's power to lift the water up.
(A modern-times alternative, which can reach quite astonishing lifting
heights even when just a small height difference is available in the
water source, would be a hydraulic ram.)
