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


New Water Quality Assessment ANNOUNCED

MyRWA, together with the EPA, has developed a new grading system for the yearly EPA-issued Mystic River Water Quality Report Card. The new grading system provides a more nuanced understanding and description of water quality conditions based on specific water body.

Explore the 2014 water quality grade. 


Two Programs Receive Funding

Last week, MyRWA received funding from the National Fish and Wildlife Foundation for the water chestnut removal project as part of the Five Star and Urban Waters Restoration Program. Read more here. The Massachusetts Environmental Trust also announced their support for a new program to develop a Mystic River recreation flagging system. This program, a collaboration with Tufts University, will alert recreational users to safe or unsafe conditions of the Mystic and Malden Rivers. Read more here.

RECORD SETTING 2015 Herring Migration

The 2015 Herring Monitoring Program is finished for the season! Volunteers performed 680 ten minute observations and counted 57,617 fish. The observations and counted fish are plugged into a sophisticated model developed by the Division of Marine Fisheries that yields the population estimate of 477,827 +/- 40,674 for 2015. Thank you to our many monitors who helped make this program a huge success.



WANTED: Corporate Volunteers

We are seeking groups of up to 100 people to help remove water chestnut, an invasive plant, from the Mystic River while offering a fun team-building day! We supply all the materials and expertise necessary. Find out more and schedule your event by contacting




Flatbread Pizza Fundraiser

On Tuesday, September 15th head to Flatbread Pizza in Davis Square, Somerville for a Mystic River Watershed Association fundraiser. That’s right, the more flatbread you eat the more money will be raised to support MyRWA and our efforts to protect and restore the Mystic River Watershed!



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!
