PantanOS

PantanOS is your control panel for Spain's reservoirs: current levels, historical trends, and comparisons with previous years, all in a single app.

📊 Weekly data taken from the MITECO (Ministry for Ecological Transition and the Demographic Challenge) Hydrological Bulletin
🗺️ Interactive map with GPS pins for over 600 reservoirs: zoom, pan, and automatic grouping by basin, autonomous community, or province
💧 Water uses: see how the capacity of each reservoir is distributed among supply, irrigation, hydroelectric power, flood control, and other purposes — at the national level, by basin, community, or province
📈 Historical graphs since 1988 with seasonal percentile bands
🌵 Water stress panel: reservoirs below their usual seasonal range
📊 Biggest weekly changes: which reservoirs are rising and falling compared to last week
⭐ Favorites: mark your reservoirs and access them from the main screen
📍 "Your area": ​​personalize the app according to your autonomous community or GPS location
🔌 Mode Offline: Data is always available, even without an internet connection.

Data is published weekly on Tuesdays from the official source, and PantanOS automatically downloads it in the background when you have Wi-Fi.

How much water is in the Ebro River? Is your province's reservoir above or below the historical average for this time of year? PantanOS gives you the answer instantly.
