What you need to know about the massive Oroville dam emergency in California
California is trying to avert disaster at the tallest dam in the United States. With the possibility of more rain on the way, engineers are working as quickly as possible while evacuees are uncertain when they will be able to return home.
Crews prepare the main spillway for resurfacing and work on the splashpad in this video from mid-April. The Oroville Dam spillway was damaged in February 2018, causing the evacuation of nearly 200,000 people.
