Update (8:36 p.m. PST): The Butte County Sheriff announces that county jails are being evacuated to other prison facilities; shelters are being opened for displaced residents; and Butte College facilities and buses will be shut down on Monday. A statement on Facebook indicates the situation at the dam is precarious: “The next several hours will be crucial in determining whether the concrete structure at the head of the auxiliary spillway remains intact and prevents larger, uncontrolled flows.”
Update (8:48 PST): Mark Finan of local NBC affiliate KCRA reports that the level of the lake has dropped to near 100% capacity — just over 901 feet above sea level — such that flow has effectively ended over the emergency spillway.
