Celebrating Progress Towards a Healthier Columbia Slough


Slough Regatta flags   Mayor Hales speaking at Regatta

This year's Columbia Slough Regatta was a great success, with over 450 people coming out to paddle on the Slough for the 20th anniversary event on August 3.

Mayor Hales and city staff touring the SloughSpecial thanks to Mayor Charlie Hales and his wife Nancy for joining BES staff for a paddle tour of restoration project sites along the Slough.  

Efforts like the Combined Sewer Overflow Control Program, replanting trees and shrubs along the bank through Watershed Revegetation, and constructing wetlands to filter stormwater are bringing back healthier conditions in the Slough.

See an example of revegetation results along the Columbia Slough in this post: Before and After: Heron Lakes
