The City of Sonoma has declared a Stage 1 Water Shortage | Water customers are urged to reduce water use by 15%

Current Drought Information

Due to historically low rainfall and continued dry conditions, our region is facing the second consecutive year of drought. A reduction in water use through voluntary conservation measures by the City’s water customers is needed to preserve critical water supplies. The ordinary demands and requirements of water consumers cannot be satisfied by the water supplies available to the City without depleting the water supply to the extent that there would be insufficient water for human consumption, sanitation, and fire protection.

City Council unanimously voted to declare a Stage 1 Water Shortage at their June 7, 2021 meeting. Effective immediately, all Sonoma residents, businesses, schools, and City facilities are urged to cut their indoor and outdoor water use by at least 15%

Water Supply

The City of Sonoma relies on Sonoma Water, the region’s wholesale water supplier, for approximately 90% of our water supply. The majority of Sonoma Water’s water supply water comes from the Russian River. Sonoma Water distributes this water through an aqueduct system to water contractors in Sonoma and Marin counties, including to the City of Sonoma and the Valley of the Moon Water District in Sonoma Valley. The State of California, and the Russian River in particular, is in the second consecutive year of extremely dry conditions due to historically low rainfall totals. Lake Sonoma provides water to the Russian River.
