This map shows how communities are listed in California's nine-tier system that penalizes the state's biggest water users.

Water suppliers are assigned to a tier -- displayed in the circles above -- of water reduction based on three months of summer residential gallons-per-capita-per-day data. The tier listings are part of the state water board's revised drought regulations that cut conservation targets for communities with a history of conservation and slightly increased cuts for communities that have used the most water..
