1997 Feather River Valley Flood: California's Costly Deluge

Yes, the Feather River Valley in Northern California suffered a catastrophic flood in January 1997.

Event Summary

• Cause: A series of warm, subtropical "Pineapple Express" storms dropped 20–40 inches of rain on heavy snowpack in the Sierra Nevada.
• Result: Feather River and tributaries overtopped levees; Yuba City, Olivehurst, Linda, Arboga inundated.
• Impact: 3 deaths, 38,000 evacuated, 10,000+ homes damaged/destroyed, $1.8+ billion in losses (1997 dollars).
• Response: Massive federal/state disaster declaration; levee system reevaluation.

The 1997 flood (and a similar 1986 event) drove major investments in the Sacramento River Flood Control Project, including setback levees, flood bypasses, and improved forecasting.
