The Clackamas River Basin Council is pleased to present:

About the Conference:

On March 9, 2021 the Clackamas River Basin Council launched a year-long series of free seminars about our unique watershed and its natural resources, from the river’s birth in alpine springs to its confluence with the Willamette River.

Subjects range from geology, water quality and forestry to fish, recreational, cultural and public policy issues. The series consists of 33, one-to-two hour sessions, taught by local and internationally-recognized experts.

The Clackamas provides drinking water to more than three hundred thousand humans who live and work in suburban Portland and is a resource, classroom and playground for tens of thousands more, including conservation professionals, anglers, rafters, boaters and other outdoor enthusiasts as well as timber producers, nursery farmers, agricultural landowners and many others.

Attending the Conference:

There is no charge for the seminars, which will be held via Zoom. Register for ALL CLASSES by clicking THE BUTTON below.
