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.

Keep Lake Whatcom in Mind When You Mow this Spring

Gather your grass clippings! Your unmanaged grass clippings may add nutrients like phosphorus to our waterways and Lake Whatcom. Nutrients feed algae blooms, which can harm water quality and wildlife. You can help manage your clippings by using FoodPlus!, bringing them to a local disposal service, or composting at home using a contained system. Go to to learn more.
