A green layer of algae stretches far out into the tide flats and piles up on beaches, where it contributes to unpleasant odors and bacteria growth, organizers said.
Such blooms are common and natural in coastal marine waters, but can be harmful when large and persistent, as is the case with marine biotoxins building up in shellfish.
Birch Bay Watershed and Aquatic Resources Management District, Whatcom Marine Resources Committee, and the Whatcom Watersheds Information Network are the event sponsors.
