These outputs are predictions of E. coli levels, based on real-time data that the CRWA collects about the weather and the streams flow of the Charles River.
The model reports E. coli predictions by reach. Hover over the info icon to see which boathouses are associated with each reach.
The model only predicts E. coli, not combined sewage overflows (CSOs) or cyanobacteria blooms. These events may leave the Charles River unsuitable for recreational activities, even when the predictive model has a "safe" prediction.
