Arrowhead & Somerset

June 29, 2026 - Avion will not be following Arnold Irrigation's early season shut off on Wednesday, July 1st, 2026. The Arrowhead and Somerset Irrigation system was designed to reduce irrigation delivery in order to keep household domestic water pressure within plumbing requirements. However, if there are curtailments to other irrigation districts or Avion's system is unable to maintain domestic pressure, a re-evaluation will be required.
