Yesterday was the very first calendar day of the summer and hopefully all the cyanobacteria blooms reported in Tuftonboro, Wolfeboro, The Broads, Governor's Island, Meredith, and Center Harbor will dry up and disappear, quickly.
Time will tell what's happening with the green/blue cyanobacteria blooms? I was swimming in Meredith and the water seemed less clear than usual, and more difficult to see the rocky lake bottom. The water was obscured with less visibility but there was no green/blue growth on the water surface? With water temp at 68 and air temp a sunny humid 92-degrees, it was a happening swim in the lake.
Swimming the lake is different from swimming a pool, and wearing a swim flotation belt is a good suggestion for swimming the deep water with the waves, wind, and wakes.
