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.

Be Safe and Watch Your Wake

It's summer finally! 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.

Check your motor before 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 Check Your Motor page to learn more.

Update: Electric Avenue Bridge Partially Reopened

Following a one-week full closure, the Electric Avenue bridge over Whatcom Creek is now open to one lane of traffic, controlled by temporary traffic signals and a 24-ton weigh limit. This temporary solution is necessary due to critical structural issues identified in a recent inspection. Engineers are currently working on a long-term solution and it may be some time before you see active construction on the bridge. Pedestrian access remains open on the east side sidewalk and bicycles should share the traffic lane and obey traffic signals and all traffic laws. Planning and funding efforts are underway for a full bridge reconstruction project. We will keep the community updated on the progress through the Electric Avenue bridge project webpage.  

Impacts to Lake Whatcom and Lake Samish This Summer

This year there are several construction improvements coming to parks and boat launches in Whatcom County. Be aware of these projects and plan your trips accordingly!

Bloedel Donovan Construction - Starting June 3, Bloedel Donovan Park will be impacted by construction as crews replace electrical lines and stormwater infrastructure around the Bloedel Donovan Multipurpose Room. The project is expected to be completed in the Fall. Park and lake access, boat launches, swim docks, the Bloedel Boathouse, Whatcom Rowers building, playgrounds, and restrooms will also remain open during construction. Find more information and answers to frequently asked questions at Bloedel Donovan Building Renovations.

Lake Samish Bridge Construction - Starting June 3rd 2024 and running until Summer of 2025, Lake Samish Park will be closed for the N. Lake Samish Bridge Replacement Project. Additionally, the pedestrian bridge along the lakeside trail near the boat dock will be closed and repaired during the parks closure. Boat launches are open but access to the western basin of Lake Samish will be closed. For more updates and information, visit Whatcom County’s N. Lake Samish Bridge project page. 

South Bay Boat Launch Closure - Lake Whatcom’s South Bay boat launch will be closed to all traffic from Monday, June 3 to Friday, June 14 while it is being paved. The boat launch is scheduled to re-open Saturday, June 15.
