Overview
- Aichi approved a seventh round of rationing that cuts farm supply by 50%, tap water by 30%, and industrial use by 50%, affecting households, growers, and manufacturers across the Toyokawa service area.
- Shizuoka Prefecture, Aichi Prefecture, and Japan’s Chubu Regional Development Bureau set a three-party meeting to coordinate water use across prefectural lines with portions of the session closed to the press.
- Officials plan to activate the Koda–Gamagori interconnection to draw water from the Yahagi River system, with a reported capacity of about 5,000 cubic meters a day, which would be the first drought-time use of the link built for emergencies.
- Aichi will ask Shizuoka to support emergency transfers from Sakuma Dam on the Tenryu River system, though any relief faces limits on how much can be moved and how fast it can be delivered.
- Record low rain in a small basin with little snowmelt left Ure Dam at zero storage and now puts Oshima Dam at risk, with only 43 millimeters through March 24 compared with a 199 millimeter norm.
