Authorities say three members of a family were injured, one critically, when they were ejected from the log ride at a Southern California amusement park.

Fire officials say the ride malfunctioned and one of the log-shaped vessels overturned Saturday at Castle Park in Riverside.

Officials say riders were thrown from the vessel and trapped in the water.

Fire Capt. Brian Guzzetta says a woman was hospitalized in critical condition. A man and 10-year-old boy were treated at a hospital for minor injuries.

Guzzetta says a pump apparently malfunctioned, preventing the flow of water onto the track. He says when the log descended from one of the falls, there wasn�t enough water to slow it down and it crashed.

The log ride is closed during an investigation but Castle Park will remain open through the weekend.
