I keep going to the NHDES website on cyanobacteria and find no notices for Winni at all.

The seems to be a disconnect here. Am I looking in the wrong place? Are we talking about different kinds of cyanobacteria?

Your neighbor may be referring to the precursor to cyanobacteria "poisonous blue-green algae blooms", which are the
gloeotrichia. Those are the tiny gray dots that come within easy view of the surface on warm and windless days In late summer.
As a sailor, I have many hours on Lake Winnipesaukee on warm, windless, days in late summer.
I can tell you
gloeotrichia are easy to see and they're all over the lake.
At night, their natural buoyancy mechanism allows them to sink to deeper waters where they recharge their energy on Phosphorus.
Nobody's come right out and said it (yet) but all
that Phosphorus has a common origin.

One Maine organization is collecting
gloeotrichia data by means of a smart-phone app:
