In Marysville, the body of a man, missing since Sunday, was found in Ellis Lake.
25-year-old Eduardo Lopez was reported missing by his girlfriend.
He has reportedly been walking home from a local bar Saturday night but never turned up at home.
The Marysville Police Department and the Yuba County Sheriff's Office combined efforts in searching for Lopez.
His cell phone data led them to the lake and a dive team, aided by sonar, helped them find the body.
Foul play is not suspected.
An autopsy will be scheduled to determine how he died.
