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.

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.
