Sensitive eelgrass habitats are nurseries for juvenile Chinook salmon as well as spawning areas for Pacific herring – small schooling fish that support seabirds, big fish, and marine mammals. Eelgrass damaged by boat anchors can take years to recover. To help salmon and the endangered Southern Resident orcas, avoid herring spawning grounds, anchor out in waters deeper than the eelgrass, or use a mooring buoy when staying outside a marina. While eelgrass is present at most popular anchorages in the San Juans, in many locations the shallow meadows can be easily avoided by anchoring in waters deeper than 15 feet.

Boaters can help protect marine mammals by keeping your distance, reducing speeds, and turning off fish finders and echo sounders when not in use. Do your part to keep marine waters clean by using pump outs, making sure your boat is in good working order, and quickly cleaning even small spills. Stay up to date with local regulations around marine mammals at bewhalewise.org.
Use the detailed information found in this boater guide to plan ahead and ensure your boating experience in the San Juan Islands is safe and enjoyable for people and nature!
