About river water level alarm system

This system installs a water level gauge at the confluence of Katabira River and Ima-Igawa rivers (near Ima-Igawa Kawaguchi Bridge) and informs residents of the dangers of floods using a two-step siren sound.

When the water level exceeds the sounding water level (160 cm) of the first stage siren, the pat light at the Kawaguchi Bridge Water Level Station lights and rotates, and the siren is sounded at the speaker station.

Information on water levels at Ima Igawa Kawaguchi Bridge, which is near the confluence of Katabira River and Igawa rivers, is provided by automatic voice using the following numbers.
