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.

Lake Whatcom Watershed Work Window Closes

September 30th is the last day of the work window for ground disturbing activities in the Lake Whatcom watershed. Ground disturbing activities include clearing vegetation, adding topsoil or fill, and other activities that move or expose soil. Special regulations apply to prevent erosion during the rainy season from October 1st to May 31st. Dirty water flowing into Lake Whatcom adds phosphorus, harming water quality and aquatic life.

Fires Being Managed in South Lake Whatcom; What to Know

*The Blodel Donovan and Sudden Valley boat launches have reopened as of 9/3/2023 

The Bloedel Donovan Park and Sudden Valley boat launch will be closed and boating traffic not allowed until further notice to keep Lake Whatcom clear while fire crews fight wildfires on the lake’s southeast shoreline, likely caused by lightning Monday evening.  In addition, Whatcom County’s Hertz Trail on Lake Whatcom is closed and Blue Canyon Road is closed at South Bay Drive and Park Road; please do not drive past road closed signs. Officials also ask that drones stay clear of wildfire fighting efforts to ensure firefighting aircraft are not hindered in their response. State Department of Natural Resources ground and aerial firefighting teams are onsite, with support from other agencies. A Level II evacuation advisory has been issued to alert Blue Canyon Road residents to prepare for possible evacuation. Please respect the closures and advisories that are in place for public safety and protection. See Whatcom County Sheriff's Office for more information.
