A car drove into the Rogue River from the boat ramp at Pierce Riffle Park Sunday afternoon, and a private citizen with a jetboat pulled the driver out of the partially submerged car a short distance downstream.

According to Josephine County Sheriff Dave Daniel, the lone occupant of the car was a 54-year-old woman.

The car is still in the river downstream of the ramp, partly submerged. Pierce Riffle Park is three miles east of Grants Pass, accessed by Averill Drive.

When ambulance and fire crews arrived, the woman had been rescued already, and was taken to Asante Three Rivers Medical Center for evaluation. Daniel said she was placed under a peace officer mental hold.

Grants Pass Fire and Rescue, Rural/Metro Fire Department and American Medical Response ambulance responded.

The Sheriff's Office is investigating.

A similar incident occurred at Schroeder Park in March of 2016. A car was driven — or pushed — into the river from the boat ramp and was swept downstream about three-fourths of a mile where it sunk.

The car was pulled out of the river nine days later. No one was ever found in the car.
