International Space Station crewmember Sergey Ryzhikov captured this image of Lake Oroville and the Oroville Dam. To decrease reservoir levels and prevent a collapse of the emergency spillway following high amounts of precipitation earlier in February, water continues to be released from the main spillway. A state of emergency was declared on February 13th after the spillway was discovered to be damaged and the threat of its collapse caused the evacuation of more than 100,000 people downstream of Lake Oroville.
