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 Open

The work window for ground disturbing activities is open from June 1st through September 30th 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.

Thank you for timing your work to prevent erosion!

Look for the Zero

Thinking about fertilizing your lawn this spring? Remember to look for the zero! Local laws prohibit using fertilizer containing phosphorus in the Lake Whatcom watershed. Fertilizer products list three numbers from left to right for nitrogen (N), phosphorus (P), and potassium (K).  Make sure the middle number is zero. For more information, Phosphorus: Too Much of a Good Thing.
