We are pleased to announce that Snohomish County and the residents of Lake Roesiger were awarded an aquatic invasive plant grant from the State Department of Ecology. The goal of the grant is to implement the approved Integrated Aquatic Vegetation Management Plan (IAVMP) for Lake Roesiger. This grant is in the amount of $75,000 over two years and will supplement funding provided by lake area residents and the County.
