Celebrating 75 Years of Service

It has been the work of Sonoma Water since 1949 to effectively manage the resources in our care for the benefit of people and the environment. With more than 200 dedicated professionals who work for Sonoma Water in a variety of fields ranging from engineering to biology, we strive to look forward, beyond today’s issues, to anticipate ways to advance our mission:

To provide reliable water supply, wastewater management, and flood protection — essential services for a thriving community and a healthy environment. 

Celebrate Earth Day with Us

Join us at Santa Rosa’s Earth Day Festival on Saturday, April 20 from noon to 4 p.m. at Courthouse Square.

This FREE, family-friendly, zero waste festival brings the community together through fun activities, live performing arts, great food, and inspiring exhibits that raise environmental awareness including activities with our Water Education team and our four-legged friends at Mussel Dogs who sniff out invasive species of mussels up at Lake Sonoma and Lake Mendocino.

Eco-Friendly Garden Tour - Registration is Now Open

Don’t miss the 14th annual Eco-Friendly Garden Tour on Saturday, May 18! This self-guided tour, hosted by the Sonoma-Marin Saving Water Partnership, focuses on low water use and sustainable landscaping at 26 inspirational gardens throughout Sonoma and Marin counties, including the personal gardens of local landscape designers, architects and garden enthusiasts. If you are interested in landscaping your yard like the pros, or simply looking for fresh ideas for future landscaping projects, the garden tour is the perfect event for you!

Mulch Madness

Get in on #MulchMadness this spring by adding wood chips or yard clippings around plants. It helps soil retain water, reduces the need for watering, inhibits weed growth, moderates soil temperature, and prevents erosion—keeping your yard in winning shape!

The Last Coho Photography Show

The Laguna de Santa Rosa Foundation is hosting The Last Coho, a photography exhibit of work by local photographer Kaare Iverson, combining portraiture of endangered salmon with editorial excerpts that collectively illustrate the incredible effort to rehabilitate Coho in the Russian River Watershed. Many of the portraits were shot on large format film using an heirloom land camera which the photographer inherited through a connection to Ansel Adams.

The Last Coho by Kaare Iverson will be on display at the Laguna Environmental Center’s Heron Hall, 900 Sanford Road, Santa Rosa from May 4 through August 30, 2024. The public is invited to attend a free opening reception with the artist on May 4, 3 – 5:00 p.m.
