US officials on Monday found the body of Glee actress Naya Rivera in the Californian lake where she drowned last week during a boat trip with her 4-year-old son.

Rivera's body was retrieved and an initial examination found no evidence of foul play or suicide, Ventura County Sheriff Bill Ayub told a press conference.

"We are confident the body we found is that of Naya Rivera," said Ayub, pointing to the location, appearance, clothing and condition of the body.

Her body was being taken to a medical examiner's office for a full autopsy and confirmation of her identity from dental records, though no other missing persons have been reported at Lake Piru, he added.

Rivera, 33, is believed to have accidentally drowned after renting the boat with her young son at the recreational hot spot around an hour's drive northwest of Los Angeles.

Rivera was best known for her role as high school cheerleader Santana Lopez in Glee.

She starred for six seasons in the wildly popular musical series.
