Lake Kanasatka was resampled this weekend, and samples were reviewed today, 10/3/2022. The cyanobacteria density has decreased from last week, but is still visually present as flecks suspended in the water column, observed around the waterbody. A sample from the West side had a density of 42,800 cells/mL, and the dam area had around 14,066 cells/mL. A scum was reported after sampling, but was not sampled. The continued presence of fairly high cyanobacteria indicates the potential for surface scums to form under the right conditions. We will be keeping the advisory in place for another week to make sure densities decrease further. The cyanobacteria present in samples was primarily Dolichospermum (several species) and Apahnizomenon.
Please keep signs posted at public access points. NHDES will review samples again in a week. If people ask for updates on the current cyanobacteria advisory status, please direct them to the Beach Advisories Mapper
. If you click on the advisory symbol, you can see our most recent sampling date. When advisories are lifted, the red symbol for the waterbody will no longer be on the map. Please forward to other residents / community members around the waterbody, and provide me with any contacts (first and last names, and emails) of folks who want to be directly included on future communications from NHDES.
Thank you to folks helping with resampling and reporting efforts!
