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


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!



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.

Stormwater Forum Sept. 10

The Belmont Citizens Forum is holding a free, public, educational forum on stormwater called Water Trouble: A Neighbor-to-Neighbor Dialogue about Storms, Floods, and Water Quality, on Thursday, September 10, 7-9 pm, at Winn Brook School in Belmont. Belmont, Arlington and Watertown neighbors will have a conversation about stormwater and how it affects these towns. The panel of experts, including MyRWA's Patrick Herron, will discuss stormwater projects and issues relevant to all three towns, as well as green infrastructure, water quality and rivers, and infiltration strategies for urban soils.


Preserve the Mugar Wetlands

The Mugar property is a triangle of land near Thorndike Field, across Route 2 from Lanes & Games in Cambridge.In a recent policy letter, MyRWA weighs in on the housing project proposed by Oaktree Development for the Mugar property in East Arlington. The development would significantly degrade the ecological and hydrologic value of the site and would further stress the already impaired Alewife Brook watershed. For these reasons, MyRWA strongly opposes the proposed development and supports efforts to preserve the property as open space, as outlined in the Town of Arlington’s newly adopted Master Plan.



Water Chestnut Removal Going Strong

Click for a 34 second time-lapsed videoWe have a few final water chestnut removal events left in 2015, and have already removed more than 3,000 baskets of the invasive weed! Community and corporate water chestnut hand pulling events help eradicate this invasive species which thrives in the Mystic River. Learn more and get involved 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.




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!
