Slough 101 Workshop

March 10, 2014

Learn all about the Columbia Slough Watershed and its unique history!

The Columbia Slough is a beautiful 60-mile long floodplain of the Columbia River. Previously, Native Americans lived along the wetlands.  Today, ten percent of all jobs in Oregon are located around the Slough.

Slough 101 is a free workshop that covers watershed health, environmental issues, wildlife and history of the region.  Participate in hands-on activities and go on levee and pump station tours. Eight local experts will be on hand to answer a range of questions, from where to see Great Blue Herons to flood management. 

Slough 101 is on Saturday, March 15, from 9 am – 12:45 pm at the Multnomah County Drainage District.  Light refreshments are provided.  Please register on the Columbia Slough Watershed Council’s website.
