Columbia Slough Watershed Council



The Columbia Slough Watershed Council’s Stewardship program is dedicated to improving watershed health by combining local residents, natural areas, and restoration activities in locations throughout the watershed.  Volunteer activities include native plantings, weed pulls, and litter cleanups in and along waterways.

Stewardship Saturday

Stewardship Saturdays are morning work parties in local parks and natural spaces. Activities range from invasive species removal to litter pick up, native plant planting, mulching, trail maintenance and more. We provide tools and training - no experience is necessary!

Check out and register for our 2018 Stewardship Saturday events below!

All events take place from 9:00am - 12:00pm.
