The Mystic River Watershed Association is excited to announce that Boston-based multidisciplinary artist Andres Duarte has joined MyRWA as our Mystic River Artist in Residence from now until spring 2026.

A big year for water quality in the Mystic River watershed has kicked off this January, first with a public meeting about Combined Sewer Overflows and now with upcoming meetings and public comment periods for two highly significant draft permits from the EPA. Resulting from a decade of hard work to better understand water quality in the Mystic, these permits will enforce stormwater pollution regulations and pave the way for a cleaner Mystic River for generations to come. Join us at the next public hearing on January 28th at 6:30 pm to make your voice heard for clean water.

In 2025, we look forward to lots of exciting progress along the Mystic Greenways. Learn more about the many projects aimed at creating safe and accessible routes for walking, biking, rolling, and exploring scheduled to open or be ready for construction before the year ends.
