Lake Kanasatka was resampled this weekend, and samples were reviewed today, 10/10/2022. The cyanobacteria density has increased again and formed visual surface scums in some locations. A sample from Sandy Cove had a density of 407,900 cells/mL, and the dam area had around 22,200 cells/mL. The cyanobacteria present in samples was primarily Dolichospermum, Apahnizomenon, Woronichinia and Microcysits.
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 efforts!
