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.

Watershed Work Window Opened June 1

Are you planning a home improvement project in the Lake Whatcom watershed? Keep in mind that certain projects that disturb or expose soil can only be completed during the “watershed work window” from June 1 to September 30 each year. Limiting projects that move and disturb soil—such as construction and landscaping changes—to dry season months reduces the chance of rainwater washing soil particles into the lake. Special requirements vary by project type, size, and scope. Before starting any home improvement project, be sure to contact your local permitting center to learn about specific requirements for your project.

For watershed residents living within city limits: City of Bellingham Permit Center (360) 778-8300

Keep Safe and Watch Your Wake

Be safe when you’re out on the lakes. Boating speed rules and no wake zones on Lake Whatcom and Lake Samish keep swimmers and boaters safe and protect the shoreline from erosion. Less erosion is better for water quality and protects shoreline vegetation and property. Review speed and safety rules for Lake Whatcom on our On the Lake Safe Boating page.

Check Your Motor. Protect Lake Whatcom.

A reminder as you head out onto the lake this season: cleaner, low emission motors are required on Lake Whatcom and Lake Samish to protect water quality. Look for the label on your motor and make sure it has at least one star. Visit our On the Lake page to learn more.
