===Oroville Dam crisis===
{{main|Oroville Dam crisis}}
On February 7, 2017, after heavy rains, a defect formed in a spillway of [[Oroville Dam]]. For the first time since its construction, the secondary spillway was overtopped on February 11. Shortly after being put into service, this structure began to show signs of being undermined, raising fears of catastrophic failure. Owing to their inability to predict the continued safety of this spillway, the Butte County Sheriff ordered evacuations of downstream residents from Butte, Sutter, and Yuba counties.<ref>{{Cite news|url=http://www.kcra.com/article/evacuation-orders-issued-for-low-levels-of-oroville/8735215|title=Thousands from Yuba, Butte, Sutter counties evacuated|author=KCRA Staff|date=February 13, 2017|newspaper=KCRA|access-date=February 13, 2017|language=en}}</ref>
