Authorities fear the worst for a teen who fell out of a raft Wednesday evening near the Thermalito Afterbay. Eyewitnesses say the 17 year old went underwater near the Afterbay outlet on the Feather River Wednesday evening about 5:30. Rescue Crews looked for him during the evening hours and tried again Thursday morning but water flows were deemed too dangerous. It's unknown when the search will resume but rescuers don't hold out much hope for the teen boy.
