<P>PROBLEM TO BE SOLVED: To provide a natural river power generation system using the uneven river bed of a natural river for generating power from an almost all water flow even when there is a small amount of water in the river. Ž<P>SOLUTION: The natural river power generation system includes a water power generation device 10 to be installed on the river bed of a lower step portion of a river between both banks in the state of packing both banks with concrete and setting its ceiling part flush with an upper step portion of the river. The water power generation device 10 consists of a waterfall 20 having a waterfall path at the bottom center and a V-shaped waterfall slope 22 formed toward the waterfall path, at least a pair of water turbines 25 to be installed under the waterfall slope for receiving waterfall from the waterfall slope to change the kinetic energy into rotating motion, a power generation chamber 30 storing a power generation device and continuously provided on the upstream side of the waterfall 20 for transmitting the rotating motion of the water turbines 25 to generate power, a waterfall guide block wall 40 having a water discharge path 41 formed on the lower side in communication with the waterfall path and continuously provided on the downstream side of the waterfall 20 for guiding waterfall to the water turbines 25, and a movable dam 50 for damming a water flow over the ceiling part and discharging water.
