A wrongful-death lawsuit has been filed over the drowning of Glee actor Naya Rivera, who died this summer while boating with her 4-year-old son on a California lake.

The suit, filed on November 17, blames Ventura County and managers of Lake Piru for her accidental death on July 8 at the lake north-west of Los Angeles. It was filed on behalf of her son, Josey Hollis Dorsey, by Ryan Dorsey – Rivera's ex-husband and the boy's father and guardian – and also on behalf of her estate.

Rivera, 33, had rented a pontoon boat on the lake. Her son was found sleeping and alone on the drifting boat later that afternoon. Rivera's body was found in the lake five days later.

An autopsy report said Rivera was a good swimmer and listed her death as an accident.

But the lawsuit said negligence was involved. It said the pontoon boat lacked a safely accessible ladder, radio, rope, anchor or other equipment to keep swimmers from being separated from the boat.

It also didn't have a life preserver or other flotation or life-saving devices, according to the suit.

The man who rented Rivera the boat has said she declined a life vest, but he put one aboard anyway.

The suit also said there weren't any signs in the area warning “of the lake's strong currents, low visibility, high winds" and other dangers even though at least 26 people have drowned there since the lake opened in 1959.

“While Naya and Josey were swimming, the boat started to be carried away – likely by the current and wind, which gusted up to 21 miles (33 kilometres) per hour that afternoon,” according to the lawsuit.

Inaccurate reports had said that Rivera boosted the boy back aboard the boat but he managed to get aboard by himself, according to the suit.

The boy heard Rivera cry for help as she struggled to get back to the boat before she disappeared, the suit said.

Rivera may not have known that her son had made it to the boat “but she surely knew that she was dying and would not make it back to her son," the suit contends.

A call seeking comment from Ventura County wasn't immediately returned on Wednesday night. A county representative declined to comment to Fox News, saying the county hadn't been served with the lawsuit.
