Charles River Watershed Association's Water Quality Notification Program presents the daily flag colors of the river's health, which signify whether or not the river is safe for boating at twelve boating locations from Watertown to Boston. Water quality flag colors are updated each weekday from early July through mid-October.
A blue flag indicates safe boating conditions.
A yellow flag indicates inconclusive data to predict possible health risks.
A red flag indicates likely health risks.
