(AP) — Authorities planned Friday to renew the search for “Glee” star Naya Rivera, who is believed to have drowned in a Southern California lake while boating with her 4-year-old son.

Rivera, 33, disappeared after renting the pontoon boat for three hours Wednesday afternoon and taking it out on Lake Piru in Ventura County, the Sheriff’s Office said Thursday.

The lake an hour’s drive from Los Angeles was searched by dozens of people, most of them divers, with help from helicopters, drones and all-terrain vehicles. The search to recover Rivera’s body continued into the night Thursday before ending for the day.

The area where the boat was found is about 30 feet deep. Murky waters heavy with plants made it difficult for divers to see more than about a foot ahead of them, sheriff’s Sgt. Kevin Donoghue said Thursday.

“If the body is entangled on something beneath the water, it may never come back up,” Donoghue said.

Rivera played Santana Lopez in 113 episodes of the musical-comedy “Glee,” which aired on Fox from 2009 until 2015.
