CC BY-NC-ND Quick Links Gloeotrichia (pronounced “glee-oh-tricky-ah”) echinulata is a colonial cyanobacteria (FKA blue-green algae) that forms tiny spheres, which can be seen without magnification in lake water. “Gloeo” has been known to exist in Maine lakes for many years, but it has typically
Metaphyton Quick Links Metaphyton is a term used to describe free-floating, filamentous algae typically observed in shallow littoral areas of lakes, where it can become entangled in the stems of rooted aquatic plants (macrophytes). Metaphyton is often characterized as having the appearance of “green cotton candy.” This filamentous algae has relatively little substance, as anyone
Other Lake Phenomena Quick Links Other Lake Phenomena There are many factors besides water quality and invasive aquatic species that can affect lake health, and the LSM helps train volunteer citizen scientists to monitors and track a number of these. Below are brief descriptions of other types of lake health indicators and links to more information.

Cyanobacteria Quick Links Water clarity is the most highly valued lake attribute in Maine.1 One likely effect of a warming climate on lakes will be an overall increase in the abundance of algae in lake water, resulting in declining clarity. As lake water warms, the conditions for algal growth are generally enhanced. Of particular concern
