Lake Kanasatka was resampled yesterday, 9/18/2022. Thank you to the volunteers who are helping with resampling efforts! The cyanobacteria density in samples from three spots around the lake have improved. The samples from near the Dam and Sandy Cove were around 6,000 cells/mL, and the sample near Kilnwood had around 12,000 cells/mL. Overall, folks have reported that the water remains cloudy in many areas, but are not seeing surface scums. The wind has also reportedly been blowing in different directions, which may be moving the more concentrated cyanobacteria material in different places than is typically observed. We will be keeping the advisory active for another week to make sure the event has fully passed.
Please keep signs posted at public access points. NHDES will review samples again at the end of this week, or early next 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 for your patience!
