COLLECT DATA FOR CLEAN WATER

Mapping Hydration/Water Refill Stations:

Plastic water bottles are one of the most frequently found litter items in our parks. Hydration/Water Refill Stations can help reduce this source of plastic pollution by providing park users with a way to fill their reusable bottles and stay hydrated while recreating. This year, we are working to create a map of all the hydration and water refill stations in the Mystic River watershed and we'd love your help! 

Baseline Water Quality Monitoring:

Join us at the MyRWA office on Saturday, April 5th from 10AM-12PM to learn how to be a part of our baseline water quality monitoring program. Volunteers in this program collect monthly data that inform our advocacy and intervention efforts to improve water quality across the watershed.

LEARN ABOUT LOCAL ENVIRONMENTAL IMPACTS

In less than 5 minutes:

  • Read our comment letter supporting an EPA permit that would regulate stormwater runoff from privately owned properties in the watershed with an impervious surface cover of an acre or more.

In 1-2 hours:

  • Hear from MyRWA and Friends of Horn Pond at the Woburn Public Library on April 28th from 6:30-8PM about improving aquatic biodiversity in Horn Pond.

  • Grab a paint brush and help refresh the mural at the Mystic Lakes Dam with us and artist Yetti Frenkel on May 3rd. This mural is a great way to learn about new places in the watershed and wildlife you might see while you explore!

In AN AFTERNOON:

  • Visit the Green Malden Fair at Pine Banks Park on April 26th from 12-3PM to learn about Malden's sustainability efforts & to recycle your unwanted items. Stop by the MyRWA table to say hi!

  • Visit the Museum of Science for their Rise Up Boston: A Climate Event on April 26th from 11AM-3PM for hands-on activities that explore the impacts of climate change. Stop by the Innovation: Earth exhibit to check out a feature on Wicked Cool Mystic!

SUPPORT OUR WORK

Help propel our work forward to protect water quality, restore important habitat, build climate resilience, transform parks and paths, and inspire youth and community members.

Sign up for our annual herring run & paddle

The Mystic River Herring Run and Paddle runs every May and celebrates the return of the river herring. The event includes a 5K run/walk race, three paddle distances (3 miles, 9 miles or 12 miles), and a bike ride with Bike to the Sea. Your participation in Herring Run & Paddle directly supports our organization and raises awareness about the incredible herring migration in our river and the importance of clean water and parks to recreate in.

donate to the mystic river watershed association

No matter the size, your donation will move important projects forward right here where we live, and in the communities we love.
