Upon arrival, Clackamas County Sheriff's deputies found a blue 1995 Ford Aspire had struck a PGE power pole located off of the roadway.
Deputies interviewed the driver of the vehicle, Zachary Fowler, 21, of McMinnville, who told them that he had been traveling westbound on Southwest Advance Road when his right front tire came in contact with the muddy shoulder of the road, causing the vehicle to lose traction and veer off the roadway, striking the PGE pole and damaging a power line.
Fowler was the only occupant of the car, and he was not cited.
He was transported to a local hospital to be treated for minor injuries.
The impact damaged a 57,000 volt feeder line, cutting power to over 11,000 customers, according to officials.
Electricity went out in an area from Wilsonville up to but not including the City of Canby. Parts of the Woodburn area were also affected.
Crews are on the scene trying to restore electrical power to the area.
There was no immediate information about the why the car hit the pole or the condition of the driver or any passengers.
