TCSameuraDamMonitor fetches dam data published by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Hydrological and Water Quality Database and displays storage rates and related data for 125 dams in Japan, including Sameura Dam. Features: * Real-time data — fetches and stores real-time data, showing storage rate, storage volume, inflow, discharge and basin-average rainfall * Storage rate messages — displays status and messages based on the storage rate, customizable * Historical data — fetches and stores past data for any period, with offline search (Sameura Dam only) * Interactive graphs — graphs for real-time and historical data (rainfall/storage rate, storage volume/inflow/discharge) * Home screen widget — check the real-time storage rate and message at a glance * Auto update and notifications — background real-time data fetching and storage change notifications Data sources: The app fetches official dam data published by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) of Japan. Real-time data is fetched by default via sudmonitor (https://sudmonitor.kusugami-lab.net), a self-hosted, non-official caching relay of the same MLIT data; the official MLIT sources can be selected instead in the app settings. Daily historical data is provided through the sudmonitor relay only. This app contains no ads, trackers or analytics. Anti-Feature (NonFreeNet): the default connection to the self-hosted sudmonitor relay is classified as a non-free network service.
