River systemSouth 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.
