CONCORD, NH — An elevated cyanobacteria cell concentration has been measured in Hopkinton-Everett Lake at the Elm Brook Park Beach in Hopkinton, according to the New Hampshire Department of Environmental Services. Samples revealed that the state threshold of 70,000 cells/ml or greater of cyanobacteria was exceeded. The cyanobacteria were identified as Anabaena and Woronichinia.
As a result, the NHDES has issued a cyanobacteria advisory at the beach area for those who recreate at Elm Brook Park Beach. The heaviest bloom areas were observed near the boat ramp and appear either as a scum on the surface or small blue-green clumps suspended in the water column. Please continue to monitor your individual shoreline for changing conditions. | More…
