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.

2023 Lake Whatcom Baseline Survey is live!

This winter the Lake Whatcom Management Program is providing the 2023 Lake Whatcom Baseline survey to watershed residents. The survey will help inform education efforts and improve services in the watershed to help protect Lake Whatcom. For those who live within watershed limits, you will receive an invitation in the mail to take the survey online. Up to four members of the household, 18 years of age and older, are allowed to take the survey. If you did not receive an invitation, it's likely because you don't live in the watershed. But if you believe you do live in the watershed and have not received an invitation, please contact us. If you have any questions about the survey, please contact at City of Bellingham Public Works.
