A submersible turbine device which can be used in conjunction with a water wheel operated at water level, away from the submerged turbine device. The submersible turbine device comprises a turbine bed and a turbine wheel which comprises a central rotor and a plurality of turbine blades. A forward shield is positioned to permit current flow on the exposed turbine blades while shielding the opposite blades of the turbine wheel. The turbine blade comprises sections which are hinged in such a manner that they automatically extend when exposed to current flow for maximum drive and that they automatically fold for minimum resistance when travelling against water pressure. A supplementary turbine device comprises anchored, upwardly extending support means, a buoyant platform mounted to the anchored upwardly extending support means for floating at the water level, and a water wheel rotatably mounted in the buoyant platform. The upwardly extending support means is adapted to permit automatic vertical travel of the buoyant platform to adjust for changes in the water level and also to provide horizontal shifting of the water wheel to coordinate with the upwards and downwards movement of the buoyant platform.
