LNU Complex

Last year, several water systems serving communities around the Bay Area suffered the effects of three massive wildfires sparked by a rare cluster of late-summer thunderstorms that swept across Northern California.

The last of the Bay Area’s major complex fires, started by lighting in mid-August, is now 100% contained. Flames destroyed 1,400 structures and killed five people.

Officials reduced evacuation orders to warnings in areas of Sonoma and Santa Cruz counties.
