The invention provides a floating ball type water level observation ruler, which relates to the technical field of observation rulers and comprises a floating block, a first measuring part, an auxiliary part, a shooting part, a cleaning part and a second measuring part, and the floating block floats on the water surface. The flexible rule is in elastic contact with the rotating shaft under the driving of the gravity of the balancing weight, the elastic block is in a compressed state, the rotating shaft is located at the position 0.2 cm below the contact switch, when the balancing weight is in contact with the water bottom, the pressure of the flexible rule on the rotating shaft disappears, and the waterproof camera photographs to complete the water depth test. At the moment, the iron core topples over, and after the iron core topples over, the measuring ruler (flexible ruler) is pulled, so that the measuring result is influenced; and during measurement, because the water bottom is not flat enough, the iron co
