The Clackamas River Basin Council is pleased to present:

On March 9, the Clackamas River Basin Council will launch 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.

There is no charge for the seminars, which will be held via Zoom. Live sessions will offer time at the end each for questions and answers. They will be recorded for viewing on YouTube at a later date if attendees cannot make the live seminar date. Registration is requested in order to provide attendees with the correct links.

We are taking donations to be able to provide this education about our watershed. If you would like to donate, please click the button below:

Below is a list of seminar subjects, their dates and content. All classes are on Tuesdays. Please visit our site regularly to see updates to this list and instructions to access each class.

  1. Seminars that begin at 6:00 p.m. are intended for a general audience. Seminars that begin at 2:00 p.m. will contain more technical content and are intended for practicing scientists, engineers and agencies personnel, although anyone is welcome to attend.
  2. Seminar prerequisites are suggestions only. Anyone may attend any class, but to get the most out of a class, the prerequisites, where noted, will be helpful.
  3. Registration information coming soon – check back here and sign up for our newsletter to receive notifications about the conference’s development: http://eepurl.com/gkj9lz
