Reference water level observatory

Tatsumi Floodgate (Koto City) is used as a reference water level observatory, and the water level (Surge Emergency Warning Water Level) is set as a reference to inform people of the danger of inundation due to storm surges. When the tide level is on an upward trend, also check the water level (outside water level) at the Tatsumi Floodgate.
