A water wheel assembly is disclosed and comprises a water wheel including a plate having a rotation axis and a plurality of circumferentially-spaced receivers, each including a first slit defined through the plate, proximal to the axis, and a second slit defined through the plate, distal to the axis. A vane is provided for each receiver and includes: a body hinged to the plate for movement between a lowered position, flush therewith, and a raised position, angularly extending therefrom; and a pair of flaps extending from the body to: project through respective slits and beyond the plate when the body is lowered; and define, in combination with the body and the plate, a scoop, when the body is raised. The plate is mounted in a flow of water with its axis normal thereto and such that the plate is free to rotate about the axis.
