Little Sandy River (Oregon)

The Little Sandy River is a tributary, roughly 15 miles (24 km) long, of the Bull Run River in the U.S. state of Oregon. Forming west of Mount Hood in the Mount Hood National Forest, it flows generally west, roughly parallel to the Sandy River to the south. Its entire course lies in Clackamas County, and most of its main stem and tributaries are within the Bull Run Watershed Management Unit (BRWMU), a restricted zone that protects Portland's main water supply.
In 2008, Portland General Electric (PGE) removed the Little Sandy Dam, the only dam on the river, while decommissioning its Bull Run Hydroelectric Project. This made possible, for the first time in nearly a century, the return of migratory salmon and steelhead to the river. In 2009, both types of fish were reported spawning above the former dam site.
