Flags
In accordance with the MA Dept. of Public Health (DPH), a cyanobacteria (blue-green algae) advisory has been posted for the Charles River Lower Basin downstream of Massachusetts Ave Bridge (a.k.a. the Harvard Bridge), with signage posted at all public access points warning against any contact with the water. Red flags are being flown at Charles River Boathouse, Union Boat Club, Paddle Boston at Kendall Square, and Charles Gate Yacht Club. Public health officials recommend that people and pets avoid contact with areas of algae concentration and, if contact occurs, rinse thoroughly.
CRWA’s water quality models are predicting blue flags at all boathouses, based only on E. coli bacteria predictions.
