Kellogg Creek Watershed

Watershed overview

Mt. Scott Creek, one of the major tributariesThe Kellogg Creek watershed encompasses about 16 square miles and is home to an amazing array of wildlife including Coho/Silver Salmon, Steelhead, Cutthroat trout, Pacific Lamprey, Great Blue Heron, Coyote, Deer, salamanders, newts, frogs, Pileated woodpecker, Wood Duck and more. The basin reaches from it's headwaters in Johnson City at Hearthwood Wetland and at Happy Valley Wetland Park in Happy Valley to the creeks confluence with the Willamette in downtown Milwaukie.

Important natural areas in watershed

  • Happy Valley Wetland Park- headwaters of Mt. Scott creek
  • Hearthwood Wetland - the headwaters of Kellogg Creek in Johnson City
  • Mt. Talbert Natural Area - a forested haven with Oregon White Oak, Cedar, and Doug Fir forests and woodlands.
  • Three Creeks Natural Area - an important wildlife area with many acres of wetlands, rare Oregon White Oak woodlands and the confluences of Dean/Deer and Phillips Creeks with Mt. Scott Creek
  • North Clackamas Park - a park situated in a floodplain and located on Mt. Scott Creek near it's confluence with Kellogg Creek. The park is also home to a small spring fed creek called Camas Creek and rare Oregon White Oak woodlands.
  • Minthorn Springs
  • Kellogg Lake - a reservoir behind the Highway 99E dam with adjacent creekside properties of Kronberg and Dogwood Parks as well as private properties.

While these natural areas help protect water quality and provide fish and wildlife habitat, the current and future health of watershed also depends on conservation activities on private land.

Key watershed stressors

At the mouth of Kellogg Creek is a dam and one of the watershed's restoration priorities. The City of Milwaukie is currently pursuing dam removal under a project called Kellogg for Coho. Additionally, Clackamas County Water and Environment Services (WES) has produced a Watershed Action Plan (WAP) for the Kellogg and Mt. Scott watershed. The Action Plan has identified these key stressors:

  • Loss of infiltration of rainwater and efficient delivery of runoff to streams due to impervious surfaces and the piped storm drainage system
  • Loss of tree canopy in riparian corridors and uplands
  • Untreated runoff from impervious surfaces
  • Floodplain development
  • Land management practices
