Gloeotrichia echinulata, or “Gloeo,” is a cyanobacterial species that has been appearing in Lake Sunapee regularly since 2004. (See LSPA’s Gloeotrichia echinulata pamphlets). Gloeo is a cyanobacterium that contains low levels of toxins and can form a thin yellowish-green layer on the lake
surface (resembling tapioca) in late August and September.
