Jug Stream, Monmouth, Maine — In a significant development, a new aquatic invasive plant species has been identified in the Cobbossee Watershed. The diligent efforts of Cobbossee Lake Association (CLA) plant survey volunteer, Cheryl Soucy, have led to the discovery of a suspicious floating leaf plant. Prompted by this finding, Watershed Friends’ surveyors, along with the Maine Department of Environmental Protection (DEP) and CLA staff and volunteers, conducted a swift follow-up survey and confirmed the presence of Trapa natans, commonly known as Water Chestnut, in Jug Stream, south of the dam. Three plants were found and subsequently removed by the Watershed Friends’ Plant Control Coordinator, Em Russell. Read more.
