The CRWA has kicked off their summer Water Quality Notification Program. This program provides the public with up-to-date water quality forecasts on the CRWA website, and will continue throughout the summer months. The website uses data from the CRWA’s weather station and other sources to estimate if the Charles River is safe for boating at each of the ten boat houses in the lower basin of the Charles. Blue, yellow, and red flags will inform the public of current water quality conditions via the CRWA website and with physical flags flown by partnering boat houses. Each week, water samples from the river will be tested for bacteria to verify the forecast. Learn more here.
