Lake Whatcom is a vital resource, providing drinking water, recreation and wildlife habitat to our community. The City of Bellingham, Whatcom County, and the Lake Whatcom Water and Sewer District formed the Lake Whatcom Management Program in 1998 to coordinate programs and projects that restore, protect and preserve Lake Whatcom and its surrounding watershed.

New Volunteer Program in the Lake Whatcom Watershed!

Do you live, work, or play in the Lake Whatcom watershed? To serve the interests of the community and protect watershed health, we have developed some opportunities to volunteer in the Lake Whatcom watershed. We are currently offering three ways to volunteer:


  1. Watershed Watchers: Activities include reporting flooding, erosion, and pollution problems, picking up litter with a provided kit, and/or keeping storm drains free of debris.

  2. Photo Sharing: Share your photos of Lake Whatcom, the surrounding forests and trails, and the people and wildlife that call this beautiful place home.

  3. Pet Waste Ambassador: help us spread the message that picking up after your pet is the right thing to do!


Visit our website to learn more. If you’re interested, scroll down and fill out the volunteer interest form. We will get back to you with more information.
