From the article:
“...The evacuation was ordered Sunday afternoon 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. ...”
Different hole than the big pothole partway down the spillway.
Chp chopper view; go to 0:15 to see water pouring over the dirt that is to the —left— of the weir...
