CommentsMultiple locations in Mansfield Hollow Lake. I observed large patches of it anchored to the lake bottom both upstream and downstream from the culvert/causeway. Countless plant segments observed floating loose immediately downstream from the culvert following a heavy downpour, suggesting that there are extensive patches upriver.
