Renamed Sonoma Water in 2018, the agency is a wholesale water supplier to nine cities and water districts that serve more than 600,000 residents in portions of Sonoma and Marin counties. In conjunction with the US Army Corps of Engineers, Sonoma Water manages and operates the Russian River water supply system.
