The Washington State Department of Natural Resources (DNR), in collaboration with local partners, is hosting a free vessel turn-in event for Whatcom County. This initiative provides an opportunity for owners of aging or unwanted vessels 34 feet or less in length, including freshwater boats, to dispose of them responsibly and prevent potential abandonment. The deadline for preapproval applications is July 1st. Approved applicants will receive information regarding the date and time for vessel turn-in. Please note that vessels 35 feet or longer are not eligible for this program.

This collaborative effort seeks to reduce the environmental and safety risks associated with abandoned vessels. By participating in this program, boat owners can ensure the proper dismantling of their vessels.

Visit the Department of Natural Resources website for comprehensive details regarding eligibility criteria and the application process.

Gather your grass clippings! Your unmanaged grass clippings may add nutrients like phosphorus to our waterways and Lake Whatcom. Nutrients feed algae blooms, which can harm water quality and wildlife. You can help manage your clippings by using FoodPlus!, bringing them to a local disposal service, or composting at home using a contained system. Go to whatcomcounty.us/yardwaste to learn more. 

On Wednesday, June 4 the Lake Whatcom Management Program hosted a second Joint Councils and Commissions meeting to provide additional time for the Bellingham City Council, Whatcom County Council, and the Lake Whatcom Water and Sewer District Board of Commissioners to further address vital issues concerning Lake Whatcom. Discussions focused on the continued collaboration between jurisdictions, particularly regarding land use, aquatic invasive species, stormwater management, and the proactive planning for wildfire impacts on the watershed.  

All meeting resources from both the April 2 and June 4 JCC meetings are now available.

June 1st is the first 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. Dirty water flowing into Lake Whatcom adds phosphorus, harming water quality and aquatic life. Special regulations apply to prevent erosion during the rainy season, and as such, the work window is only open from June 1st through September 30th. Learn more:

Whatcom County and the City of Bellingham are teaming up with ecological forestry experts to create our first-ever Lake Whatcom Forest Management Plan.

Aquatic Invasive Species (AIS) boat inspection stations officially opened April 26 for the 2025 season. We look forward to seeing you at the stations and enjoying the lakes! A 2025 AIS permit is required for all boats, canoes, rowboats and kayaks, so hitch up your vessel and swing by to get set up to safely enjoy our stunning Whatcom County lakes. Don't forget that you can earn a $10 discount on your permit by taking the AIS Awareness Course today.

Learn more and purchase your permit on the Whatcom Boat Inspections website. Please note that AIS permit fees increased this year, marking the first increase 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.

Leaves and other yard debris can pollute our water and cause flooding when managed incorrectly. Instead of piling debris where it may leach excess nutrients or block drainage, try one of the following options:

• Use FoodPlus!

• Bring them to a local disposal service

• If composting at home, use a covered and contained compost system

If you can do so safely, please clear storm drains of leaves and debris or report blocked drains:

• Whatcom County: (360) 778-6400 or report online at whatcomcounty.us/contactpublicworks

• City of Bellingham: (360) 778-7979 or report online at cob.org/SeeClickFix
