Water continues to run down the main spillway at Lake Oroville on Monday, Feb. 13, 2017, in Oroville, Calif.  The water level dropped Monday behind the nation's tallest dam, reducing the risk of a catastrophic spillway collapse and easing fears that prompted the evacuation of nearly 200,000 people downstream.  Sunday afternoon's evacuation order came after engineers spotted a hole on the concrete lip of the secondary spillway for the 770-foot-tall Oroville Dam and told authorities that it could fail within the hour.
