PURPOSE: A natural water storage system for preventing flood is provided to prevent flood by discharging overflowing river water to a river after temporarily storing the overflowing river water in a water storage tank with a non-power mode. CONSTITUTION: A natural water storage system for preventing flood comprises a flood water level forecast line, a flood water level line, a small river inlet pipe(100), a rainwater chamber(200), a first settling basin(211), a washing tank(300), a water storage tank(400), and a water level sensor. The flood water level forecast line and the flood water level line are formed in order to show the water level of a small river. The small river inlet pipe draws water of the small river between the flood water level forecast line and the flood water level line and filters the adulteration with a screen device(110). The rainwater chamber draws the river water through the small river inlet pipe and comprises an opening and a closing plate(210) on the upper end. The first settling basin filters the sludge with the movement of the river water. The washing tank gradually stores the water with a washing tank overflow protrusion(310). The water storage tank stores the water with a water storage tank overflow protrusion and discharges the stored water through a discharge pipe(412). The water sensor is included inside of the washing tank and moves the water by opening or closing the hydraulic floodgate according to the water level.
