Cyanobacteria Bloom in Lower Naukeag Lake
Lower Naukeag Lake is currently experiencing a cyanobacterial bloom that has necessitated closing that lake to boating, swimming and fishing until further notice. No cyanobacteria have been detected in Sunset Lake, which is not connected to Lower Naukeag Lake, but I want to give everyone some pertinent information.
Cyanobacteria, sometimes called “blue-green algae,” are not algae, but microscopic bacteria that are commonly found in freshwater lakes and streams. Although individual cyanobacteria are too small to be seen by the naked eye, they can form blooms that are clearly visible (see Figure below).
Cyanobacteria (blue green algae)
Cyanobacterial blooms can lead to a release of toxins and a depletion of oxygen in the water, as well as taste and odor problems.
While we occasionally see harmless green algae blooms in some of our shallower coves, cyanobacteria blooms have not been detected in Sunset Lake. I have spoken to the SOLitude, the lake management consulting firm that manages both Sunset and Lower Naukeag lakes. This bloom appears to be very localized and may have occurred due to a combination of the fall turnover (releasing lots of nutrients from the underlying sediments) occurring at the same time as the recent rain and high winds. It is not a threat to Sunset Lake, but a good reminder to always let me know (email@example.com) if you ever see anything in or around the lake that doesn’t look right.
I would like to ask that any boats, kayaks, canoes, etc. that have been in Lower Naukeag Lake anytime in the last two weeks be washed and carefully inspected before putting them into our lake.
