Kellogg Creek

Kellogg Creek is a tributary, about 4.5mi long, of the Willamette River in the Portland metropolitan area of the U.S. state of Oregon. It begins near Lake Lenore in Johnson City and flows northwest to meet the river at Milwaukie. Kellogg Creek is joined about midway along its course by Mount Scott Creek, its major tributary, which enters the main stem near North Clackamas Central Park.Mount Scott Creek and its tributaries, Phillips and Dean creeks, drain the western flanks of Mount Scott. Kellogg Creek empties into the Willamette River slightly upstream of the mouth of Johnson Creek. This is about 18.5mi above the Willamette's confluence with the Columbia River, which in turn flows about another 100mi to the Pacific Ocean at Astoria.WatershedMost of the watershed lies inside Clackamas County Service District 1. All of Johnson City as well as parts of Milwaukie and the Oak Lodge Sanitary District are also in the basin. The total area covered by the watershed is about 15mi2. Residential housing, commercial and industrial land such as the shopping mall at Clackamas Town Center, streets and highways such as Interstate 205, and pockets of high-density housing cover parts of the basin.
