A 10-year-old boy who was taken by air ambulance to a local hospital Friday night, after the Wave Runner he was riding on collided with a boat at C.J. Strike Reservoir, southwest of Mountain Home.

The crash happened near the Black Sands Resort. The boy remains in critical condition Sunday.

The sheriff's office did not release any other information about the accident. Hazel Olsen was at the resort at the time of the crash, which she said occurred just before 7 p.m. Her mother owns the restaurant at the resort.

"It was out in the middle of the lake. We heard the crash," Olsen said. She said the boy was driving the personal water craft behind the boat, catching waves, before the collision.

"He was riding behind them, having fun," Olsen said. She did not know what caused the collision. The impact knocked at least two people out of the boat, but they did not appear to suffer serious injuries, Olsen said.

People in the area on pontoon boats pulled the injured boy out of the water and brought him to shore. Olsen said he was wearing a life jacket, but had been face down in the water. He suffered serious head injuries and a laceration that caused severe bleeding.

Olsen said the air ambulance landed at the resort and left at about 7:40 p.m.-7:45 p.m.
