Welcome! Here's what's new at MyRWA...

The Mystic River Watershed Association (MyRWA) works to protect and improve environmental conditions for the more than one half million residents within the 22 community Mystic River Watershed. Read more here.



MyRWA is inspired that the state legislature has acted to empanel a commission to investigate water quality conditions in the Mystic River Watershed and to determine the ways in which water quality can be improved to support a healthy ecosystem and recreational opportunities. The thirteen member commission will include one member appointed from the Mystic River Watershed Association, the US EPA, the Massachusetts Water Resources Authority and members from the House and Senate, among others. The commission will submit a report with its findings and recommendations by July 31, 2017. The Association wants to thank the many members of the Mystic River legislative caucus and especially lead sponsors of the bill, Representative Denise Provost and Senator Pat Jehlen.

Bacterial conditions in the Mystic River Watershed. Click to enlarge.The Mystic River Watershed water quality earned a report card grade of “D” for calendar year 2013. The grade is based on bacterial contamination found in analyzed samples that were collected by MyRWA volunteers at 15 monitoring sites throughout the entire watershed. While water quality in the main stem of the Mystic River from Medford to Boston Harbor has been consistently good, a majority of the data collected in the tributary streams that feed the Mystic River indicate that water quality in those areas has remained poor. During 2013, the Mystic River Watershed met state water quality standards for boating 83% of the time, while swimming standards were met only 49% of the time.

MyRWA Selected as Root Cause Social Innovator!

Storm Sends Sewage To the Mystic

A Sanitary Sewer Overflow in Winchester MA.The Mystic River Watershed experienced significant Sanitary Sewer Overflow (SSO) events on December 10tth – the first of its kind since March 2010. The overflows resulted from the estimated 4 inches of rain received on Dec. 10th, overwhelming infrastructure and forcing overflows of stormwater mixed with untreated sewage into our waterways. Storm events of this kind are expected to increase in the future, demonstrating the need to update our infrastructure to accommodate large storm events. MyRWA anticipates that a high volume of SSO water was released into the environment and will report the data once received.

Combatting Invasive Species

For the fifth year MyRWA and partners worked together to remove the invasive water chestnut from the Mystic River. We had the most productive year yet with 6,603 baskets of water chestnuts hand-pulled from the Mystic by 941 volunteers! An additional 1,000 tons have been removed by the mechanical harvester. Read more about the Water Chestnut Removal Project here. Watch this video from Somerville Neighborhood News.


Explore Your Local Water Quality!

Is it safe to swim? What about boating? MyRWA monitors water quality throughout the watershed and is working to make the data more accessible. Using Tableau, we’ve just begun to translate the data. Please explore and let us know how we are doing!
