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.

2025 AIS Permits Now Available!

Get ready to hit the water! 2025 Aquatic Invasive Species (AIS) permits went on sale for Whatcom County lakes early this year. Inspection stations will open on Saturday, April 26, but all boats are required to have a valid permit any time they launch or operate on Lake Whatcom or Lake Samish. As always, get $10 off your annual permit and learn more about ways to prevent the spread of invasive species by taking the AIS Awareness Course today. We look forward to seeing you on the water. 

Please note that permit fees increased on March 3, 2025, marking the first increase in fees since 2019. Due to growing visitation to our lakes and increased proximity of AIS detections to Whatcom County, additional efforts are needed to protect our drinking water, recreational access, and lake health. The fee increases will help fund crucial enhancements to inspection efforts and support continued access for boaters and recreators. Permit rates vary depending on where your boat is stored. Boats visiting Whatcom County lakes from further away pose a greater risk of introducing invasive species. This increased risk is reflected in the permit prices. Resident boats will need to have an annual permit to remain on the lake throughout the season. For additional questions or to schedule an inspection on-site, please call the hotline at (360) 778-7975.
