On East and West Twin Lakes the past couple of weeks, you may have noticed clumps of algae massing in the water. The Twin Lakes Association has had samples analyzed and found that these masses contain traces of cyanobacteria, which occurs naturally in lakes in Connecticut. At low levels, cyanobacteria is harmless.
At elevated levels, however, cyanobacteria can be harmful to pets, especially dogs, and to humans, especially children. Without further testing, we do not know the level of risk that the algae masses represent.
The TLA has reported these findings to both the Torrington Health Department and the Connecticut Department of Energy and Environmental Protection. We will report back when these agencies reach some conclusions. The testing needed to assess the risk is more sophisticated than our lake management company is able to perform.
At this time, we are unable to provide guidance on the level of risk associated with the Algae bloom. We want everyone to be aware of the issue and consider taking precautions like keeping pets and children away from the algae masses, which generally are found along the shoreline.
For more information on cyanobacteria, the DEEP website features plenty of material. We suggest you take a look. We will post updates as we learn more.
