Lake Kanasatka Update September 11, 2022

Lake Kanasatka was resampled yesterday, September 11, 2022. The cyanobacteria density is back above the advisory level. A sample taken from a surface scum by the dam area had a total of 177,420 cyanobacteria cells/mL. There are three types of Dolichospermum present, as well as lower levels of Microcystis and Aphanizomenon. There was also a lot of general detritus, potentially indicating the decomposition of some of the bloom material. The non-cyanobacteria (and harmless!) phytoplankton called Botryococcus was also fairly high in samples, and could be contributing to the brown appearance of more recently observed scums and accumulated material.
