– Pet advisories were posted this morning at Bearse Pond and at Shubaels Pond (public access area only) due to “moderate” levels of Cyanobacteria observed within samples taken from these ponds A pet advisory also remains in effect at Lovell’s Pond.
– Long Pond in Marstons Mills was resampled on June 21, 2021 and the results show low concentrations of Cyanobacteria resulting in a lowered tier status. This pond is no longer under a pet advisory and the previously posted sign was removed today.
