The utility model relates to a culvert water level warning device. The device comprises a sensor, wherein the sensor is arranged in a culvert; the water level in the culvert is detected by the sensor all the time to serve as an input signal to a handrail control circuit; when the water level in the culvert detected by the sensor reaches a hazard value, the handrail control circuit is used for controlling a motor to drive an automatic handrail to drop automatically so as to forbid passing of pedestrians and vehicles. According to the culvert water level warning device, when the water level of the culvert reaches the hazard value, the automatic handrail can be automatically controlled to drop to forbid the passing of the pedestrians and the vehicles, so the final goal of the water level warning device is achieved.
