【白子川】越後山橋映像監視局[練馬区土支田4]

This camera is run by the Tokyo Metropolitan Government's flood prevention channel (東京都水防チャンネル) and watches the Shirokawa, a small river that runs through Nerima ward in western Tokyo. The view is fixed on the Echigoyama Bridge in the Toshima area, where the channel narrows and the water level rises quickly after heavy rain. The picture is a live stream, so you can see the current state of the river, not a delayed still. It is worth opening during typhoon season or after a long autumn rain, when the Shirokawa can swell and the ward issues evacuation advisories for low-lying neighbourhoods. At other times it is a quiet urban stream, useful for checking local conditions before a walk or cycle along the river path.
