UN-Habitat, WHO, and UNSD are co-custodians for SDG Indicator 6.3.1.   The Eurostat/OECD Joint Questionnaire on Inland Waters serves\n as an important data source for the indicator.  Progress reports are published every three years and global, regional, and country estimates are updated routinely.  Progress reports, a data portal, methodological details, and country files can be found on the SDG\n Indicator 6.3.1 website.
