The invention discloses a water conservancy water level monitoring pile, and relates to the technical field of hydraulic engineering. The water conservancy water level monitoring pile comprises a monitoring pile body, the upper surface of the monitoring pile body is fixedly connected with a protection box, a water level display mechanism is arranged on the right side of the protection box, and a floating mechanism is arranged on the left side of the protection box; a wind direction display mechanism is arranged above the protection box, the left side of the wind direction display mechanism isprovided with a wind speed display mechanism, and the water level display mechanism comprises a first through hole, a first support, a first movable pin, a gear, a pointer, a first supporting rod, a second supporting rod and a ruler. According to the water conservancy water level monitoring pile, the ruler fixedly connected to the side faces, close to each other, of the first and second supportingrods is matched with the pointer fixedly connected with the right side face of the gear so that the water level can be precisely displayed, technical personnel can effectively and conveniently observe the water level, the water level can be accurately judged by the technical personnel, and the use effect of the whole monitoring device is effectively improved.
