Water Quality Notification Program - Charles River Watershed Association

Project Overview

CRWA'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 ten boating locations from Watertown to Boston. Flag colors are based on E. coli and cyanobacteria levels. 

CRWA estimates E. coli bacteria levels using a model that takes into account a variety of environmental factors including antecedent rainfall and river flow. CRWA collects river samples for bacteria weekly to verify the model forecast. Cyanobacteria monitoring is conducted at least every two weeks. Read more about the development of CRWA's bacteria prediction model.

Thank you to Benjamen Wetherill of ACASAK Technologies for assistance developing and maintaining this automated system.
