Join us for our Winter River Advocates Workshop, designed for current advocates and anyone interested in learning more about the program!

Enjoy the fall weather and join us in exploring the history, current conditions, and ongoing visioning process of the Muddy River!

We'll discuss plans for retrofitting Brookline Reservoir to mitigate stormwater pollution and brainstorm 'before-pipe' nature-based solutions like rain gardens and bioswales.

Trees are a climate solution: they mitigate flooding, provide clean air, and cool our neighborhoods. Join our webinar to learn about the state of tree canopy in the Charles River Watershed and about our work to help municipalities protect, maintain, and grow our tree canopy.

Get outside this fall and join us to explore the Back Bay Fens and discover the rich history and current state of the Muddy River!

Please join us to learn about the major sources of pollution to the Muddy River, how the watershed may experience climate change, and what plans are already in the works. Join to give your feedback on what the future of the Muddy River watershed looks like!

The Massachusetts Department of Conservation and Recreation (DCR) has contracted an engineering consultant to perform an alternatives analysis study for potential future actions at the Watertown Dam. At a public meeting on September 25th, the DCR project team will present information on the preliminary results of the ongoing study and possible future alternatives for dam modifications, including the dam's removal.

Charles River Watershed Association cordially invites you to the Charles River Sunset Soirée. Mark your calendars for a beautiful evening on our beloved river aboard Charles Riverboat Company’s Charles I.

Join us on Saturday, August 24th to remove dangerous invasive Bittersweet vines!

These fast-growing, tenacious vines threaten native species & mature trees. But with your help, we can remove them & restore the river ecosystem.

At this event, water quality report card grades will be announced, and partners across the region will join us. This year, we'd like to invite the community to join us. Check back here for more details.

Join us for a tour of the Alewife Stormwater Wetland, a 3.4-acre constructed wetland that treats stormwater from 420 acres in Cambridge.

Paddle along the Charles with Professor Richard Primack, plant ecologist at Boston University, and see the remarkable sites of rose mallow plants along the Charles River.

Join us for a lunch and learn webinar about freshwater mussels in the Charles and hear from CRWA Senior Stormwater Program Manager Max Rome and Marea Gabriel, Freshwater Manager at The Nature Conservancy.

Raise a glass for restored rivers! Join us for an exciting night at Night Shift Brewing’s beer garden on the Charles River Esplanade to learn about our ongoing work to restore a clean, resilient Charles River for future generations.

Continuing last year’s great tour, join us for a walking tour along Fuller Brook, a recently restored tributary of the Charles River in Wellesley, MA.

Join us Saturday, July 13th to help us clear the Charles of invasive Water Chestnuts and restore our River!

The fast-growing, aquatic invasives spread rapidly across the river, reducing biodiversity, harming water quality, and impeding recreation. But with your help, we can remove water chestnuts & restore the river ecosystem.

Do you walk, bike, or paddle along the Charles? Cyanobacteria blooms can develop quickly, and we need volunteers like you to be the eyes and ears of our river.

Join CRWA for our Benthic Macroinvertebrate training! Volunteers wil learn how to perform a habitat assessment, properly sample for macroinvertebrates, and how to ID them. A boxed lunch will be provided to all who register!

Join Charles River Watershed Association (CRWA) and Indigenous Peoples Day Newton for a relaxing midday paddle on one of the most beautiful stretches of the Charles River.

This workshop is intended for municipal staff and their Engineering Consultants. In this workshop, CRWA staff and the University of New Hampshire Stormwater Center will highlight emerging trends and key findings from a review of 26 municipal phosphorus control plans. The workshop will include facilitated small group discussion around key strategies such as retrofits to ROW, stormwater regulations for redevelopment, and rural strategies for impervious disconnection.

For the past 4 years, 20 communities that are part of the Charles River Climate Compact (CRCC) teamed up with CRWA and Weston & Sampson to develop the Charles River Flood Model.

Join us Wednesday, June 12, at 6 PM to hear about flood mitigation solutions and their potential impact on future flooding. This event will be presented in English, but multilingual information about the project will be provided soon.

Join us for the 2024 Watertown Dam Herring Festival! Come and celebrate the annual migration of Alewife, Blueback Herring, and American Shad from the ocean into the Charles River! This migration celebration will feature a community art build, live entertainment, and fun activities for all ages!

Join us on Saturday, June 1st to remove dangerous invasive Bittersweet vines!

These fast-growing, tenacious vines threaten native species & mature trees. But with your help, we can remove them & restore the river ecosystem.

We want to hear from you! The Charles River Watershed Association and the City Of Newton will present updates on stormwater mitigation projects along the Cheesecake Brook and a progress report on restoration planning.

Join us to discuss the next projects that can help to protect and restore the Cheesecake Brook!

The Charles River Flood Model confirms that flooding will be considerably worse by 2070. Today, a so-called "10-year storm", which has a 10% chance of occurring in any given year, causes about 7,660 acres of flooding under current conditions. But, by 2070, due to climate change, the same storm event will flood 10,670 acres, an increase of over 3,000 acres that currently do not flood.

Needham, Dedham, and Boston residents, please join us to provide input on opportunities to use nature-based solutions in your community to reduce flooding and protect critical infrastructure.

Spanish translation will be provided for specific breakout groups.

The Neighborhood Association of the Back Bay (NABB) Green Committee and Charles River Watershed Association (CRWA) meeting on April 29th, 2024 discusses the primary obstacles to a clean, healthy Charles River; combined sewer overflows (CSOs), stormwater runoff, and climate change; and how we can help.
