Fir Creek (Bull Run River tributary)
River in Oregon, United States
Fir Creek is a tributary, about 5 miles (8 km) long, of the Bull Run River in the U.S. state of Oregon. Part of the system that provides drinking water to the city of Portland, it flows generally northwest through a protected part of the Mount Hood National Forest in Clackamas and Multnomah counties. It joins the Bull Run River at the upper end of Bull Run Reservoir 1, about 14 miles (23 km) from the larger stream's confluence with the Sandy River.
