PROBLEM TO BE SOLVED: To provide a water level measuring system which is inexpensive, can be installed easily, is capable measurement while crossing rivers at an observation location, and can measure an accurate water level even in rivers having a plurality of channels. SOLUTION: The water level measuring device comprises: a laser scanner that scans the rivers by crossing, and outputs an irradiation angle, reflection distance, and reflection intensity for each measurement point as measurement data; and a control recording processor, having a measurement data input section that is connected to the laser scanner and receives measurement data, a measurement data storage memory that is connected to the measurement data input section and stores the measurement data, a water level calculation section that is connected to the measurement data storage memory, reads the measurement data, and calculates water level coordinates from the measurement data, and a data communication section for transmitting the water level coordinates for each measurement point calculated by the water level calculation section to the outside.
