About PantanOS and Spain's reservoir data.
PantanOS is a free mobile app that shows the status of Spain's reservoirs using MITECO's official data. It brings together each reservoir's water level, fill percentage, historical trend and comparisons in a single dashboard.
All data comes from MITECO's Weekly Hydrological Bulletin (the Spanish Ministry for Ecological Transition). Our server downloads and processes the bulletin; the app never contacts MITECO directly.
Once a week, following the publication of MITECO's Weekly Hydrological Bulletin.
It includes every reservoir covered by MITECO's bulletin, organised by river basin, autonomous community and province so you can browse from the whole country down to a single reservoir.
