Flags
CRWA’s water quality models are predicting red flags at the following boathouses, based only on E. coli bacteria predictions: Cambridge Boat Club, and Harvard’s Weld Boathouse. Red flags are due to recent rainfall. Stormwater runoff from rain events washes pollutants, such as bacteria, into the Charles River, degrading water quality. CRWA’s water quality models are predicting blue flags for all other boathouses.
