On Tuesday September 13, 2022, a Cyanobacteria Advisory was posted by the Brewster Health Department at Lower Mill Pond due to a visible algal bloom indicative of elevated levels of cyanobacteria. The decision was made in conjunction with a recommendation by the MA Department of Public Health. The posting is at the Lower Mill Pond Dam at the Grist Mill off Stony Brook Road.
As a precautionary measure, a second posting was erected at the Lower Mill Pond Beach Association kayak launch area through the collaborative efforts of the Brewster Ponds Coalition and the Beach Association. Testing of the pond will continue on a weekly basis to monitor existing cyanobacteria levels.
Out of an abundance of caution and until further notice, people and pets should avoid contact with the pond water. Do not ingest or get pond water in your mouth. Do not recreate in this pond until the posting is removed by the Town of Brewster.
The Town and the BPC will report back when the pond is to be reopened.
Call your doctor or veterinarian if you or your animals have a sudden or unexplained sickness or signs of poisoning.
