The Basics

From its headwaters in the Mt. Hood National Forest to its confluence with the Willamette River, the Clackamas River basin encompasses nearly 1,000 square miles. The river hosts threatened and endangered species, boasts numerous recreation opportunities, and provides drinking water to almost 400,000 people.

The Clackamas River Basin Council, with diverse representatives from over twenty stakeholder groups, fosters partnerships with organizations and private individuals to advocate natural resource conservation and preserve the watershed for future generations. Stakeholders include (but are not limited to) those involved in agriculture, education, fish and wildlife, hydropower, recreation, timber production, and government agencies.

Gettin’ Fishy

  • The watershed is home to the last significant run of wild late winter coho in the Columbia Basin. The wild late run Coho generally spawn on the mainstem of the Clackamas above the North Fork Reservoir.
  • The watershed has one of only two remaining runs of spring chinook in the Willamette Basin. The watershed also supports a significant population of winter steelhead, cutthroat trout and native lamprey.

Where We Work

The Clackamas watershed is a special place. It is home to the last significant run of wild late winter coho in the Columbia Basin, and it is also one of only two remaining runs of spring Chinook in the Willamette Basin. In addition, it supports a significant population of winter steelhead. The watershed is also home to threatened and endangered species, including the peregrine falcon, bald eagle, and Nelson’s checkermallow.

20 miles of the Clackamas are classified as seasonal, and 27 are classified as recreational, for a total of 47 miles of wild and scenic river. In order for a river to become a National Wild and Scenic River, it mus have at least one resource that is considered to be “outstandingly remarkable.” Assessment of the Clackamas River found five different resource categories to be “outstandingly remarkable” — recreation, fish, wildlife, historic, and vegetation.
