The head of Three Mile Harbor, and Georgica, Wainscott, and Hook Ponds are among the water bodies that continued to be compromised by harmful algal blooms or high levels of fecal coliform bacteria.
Georgica Pond’s water quality improved last year, Dr. Gobler told the trustees, which he said was likely the result of the aquatic weed harvester that has removed macroalgae from the pond in recent summers, but dangerous blooms of cyanobacteria, or blue-green algae, occurred in Georgica Cove, New York.
