The Yoshii River System: 3 Live Cameras in Japan

The river of eastern Okayama in three cameras: right below the Shintabarai weir, at Miyasu nearer the mouth, and on a tributary four kilometres away.

What you can see

All three are fixed on one spot: two on the main stem, one on the Kongo River tributary.

Below the weir shows the reach immediately downstream of the Shintabarai weir, which dams the Yoshii. How the water falls away from the weir is visible here.

The lower gauge is a water-level station, and of the two cameras the ministry has on this main stem it is the one nearer the mouth.

The Kongo River camera is on the tributary that joins the Yoshii, less than four kilometres from the camera at the weir.

With the foot of the weir and the tributary this close together, you can compare water falling from the weir and water coming in from the side.

When to watch

Heavy rain is when these matter. Below the weir the volume falling over it is there on the screen, so you can tell how much is arriving from upstream without reading a number. Decide about evacuation from your local authority. The cameras here are for seeing how things look.

The Kongo drains a smaller area than the main stem, so it reacts to rain sooner. Open it alongside the weir camera.

The worse the day, the darker the picture, and raindrops blur the lens. Do not expect much of the image.

On a calm day the foot of the weir is the one to watch: the lower the water, the clearer it is where the falling threads gather. The operator publishes no best season, and we do not set one here.

If it isn't showing

The source is the Chugoku Regional Bureau of the Ministry of Land, Infrastructure and Transport. These are test feeds and can stop without notice. How to tell why a screen is blank is in What is happening when a live camera shows nothing.

All three are in Okayama.

The same prefecture also has The Asahi River System and The Takahashi River System. All three Okayama systems pair a main stem with a tributary, so opening them on the same day shows how differently the rain arrives.
