Q: Why are we in a Phase III Water Shortage?

  • A:  A Phase III Extreme Water Shortage has been declared due to ongoing drought conditions across portions of the District. Below-average rainfall, declining groundwater levels, and reduced river flows continue to place significant stress on regional water resources. Water shortage declarations are temporary measures used to help protect water supplies during extended dry periods. Conditions are monitored regularly, and additional restrictions may be implemented if conditions continue to worsen.  To learn more about the Phase III Water Shortage, please visit the St Johns River Water Management site at https://www.sjrwmd.com/wateringrestrictions/.
