The creek passes under Oregon Route 51 just before entering the river. The creek's mouth is about 95 miles (153 km) upstream of the Willamette's confluence with the Columbia River.North Fork Ash Creek begins at the eastern edge of the Central Oregon Coast Range near Dallas at 44°54′35″N 123°21′44″W and flows generally southeast to meet the Middle Fork. Middle Fork Ash Creek begins at 44°53′26″N 123°17′37″W near Mount Pisgah and flows generally east. Both forks pass under Oregon Route 99W shortly before they merge to form the main stem.Ash Creek is joined by a third fork, South Fork Ash Creek, in Independence. The South Fork begins at 44°52′36″N 123°18′28″W slightly south of the Middle Fork and flows generally east to meet the main stem at 44°51′13″N 123°11′36″W The South Fork passes under Route 99W south of Monmouth and under Route 51 in Independence.None of the three forks has a named tributary.

The Willamette Valley ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington. Slightly larger than the Willamette Valley for which it is named, the ecoregion contains fluvial terraces and floodplains of the Willamette River system, scattered hills, buttes, and adjacent foothills. It is distinguished from the neighboring Coast Range, Cascades, and Klamath Mountains ecoregions by lower precipitation, lower elevation, less relief, and a different mosaic of vegetation. Mean annual rainfall is 37 to 60 inches (96 to 152 cm), and summers are generally dry. Historically, the region was covered by rolling prairies, oak savanna, coniferous forests, extensive wetlands, and deciduous riparian forests. Today, it contains the bulk of Oregon's population, industry, commerce, and agriculture. Productive soils and a temperate climate make it one of the most important agricultural areas in Oregon.
