Important Dates: Lake Science programs scheduled for the next two Sundays (8/19 & 8/26) have to be CANCELLED due to illness, and we hope to reschedule them next summer


Toxic algae is a concern for lakes worldwide. We have observed algae blooms over the years in the Twin Lakes that contain the blue-green cyanobacteria that have the potential to be toxic, primarily to babies and pets. The incidence of toxic blooms in Connecticut is rare, but not unknown, and Twin Lakes has not experienced a toxic outbreak. Nevertheless, TLA tries to monitor the situation, and ask that the membership be informed and support our efforts.
