River system	South Umpqua River

Cow Creek is a medium-sized river in southwestern Oregon, a tributary of the South Umpqua River. It drains an area of over 400 square miles (1,000 km²) on the western foothills of the Cascade Range and within the Oregon Coast Range. Although the vast majority of the basin is within Douglas County, a tiny portion in the southeast extends into northern Jackson County.
