A tubing accident on a lake in Sonoma County severely injured a 7-year-old boy on Saturday, the sheriff's office reported.
The boy, his father and other people were tubing on Lake Sonoma when the boat's towline that was pulling the child on a tube was caught on a different boat's propeller. The moving propeller pulled the towline and the child toward the boat.
The propellers hit the boy's legs, severely cutting them, which led to significant bleeding, according to Sgt. Ed Hoener.
Due to the boy's severe injuries and the remote location in a restricted area of the lake, a sheriff's helicopter was brought in. The boy was treated where the helicopter landed on the lake and then transported to Santa Rosa Memorial Hospital, Hoener said.
At the hospital the boy was sent to the trauma unit to undergo surgery.
Further details concerning the accident are under investigation, according to the sheriff's office.
