What changed
Spain's Council of Ministers has approved an official catalogue of shared aquifers — underground water bodies that span two or more river basin districts. The catalogue is a technical and administrative tool to enable coordinated management of groundwater across different river basin authorities and fulfils a requirement of the 2023 hydrological planning legislation.
Who is affected
Primarily affects river basin authorities (Confederaciones Hidrográficas), regional governments, and businesses or farms that draw water from cross-boundary aquifers. Future water use restrictions or coordination measures may be shaped by this catalogue.
What to look out for
→ No action required from citizens. The technical catalogue and associated mapping are available on the Ministry for Ecological Transition's website.
