A water gauge for on-site monitoring and early warning includes an alarm part, a control part and a retractable part. The retractable part is fixedly connected with the alarm part at the top, and the control part at the bottom; the alarm part is electrically connected with the control part through a wire; the control part compares the water level measured by the retractable part with a preset threshold, to determine whether the alarm part needs to give an alarm. When the water on the road rises to the warning line of 30 cm set on the water gauge during a rainstorm, the warning light on the top of the water gauge will start to flash, and the water gauge will give an alarm through the speaker, reminding the pedestrians and vehicles not to pass the section for the time being.
