Algae Observed on Long Lake Main Basin

Gloeotrichia echinulata (a type of cyanobacteria (blue-green algae) commonly found in low-nutrient waters) can be seen with the naked eye. Gloeo density is reported as a value ranging from 0 – 6, based on the number of Gloeo colonies seen through a Secchi scope. Higher values indicate more Gloeo colonies. The middle basin’s Gloeotrichia echenulata density ranged from 0 through 3 with the highest density occurring in early August.
