Meet Victoria & Ananda, Your 2026 Graffiti/Street Artists-in-Residence

Rayven Heath

We’re excited to introduce our 2026 Graffiti/Street Artists-in-Residence at Lynch Family Skatepark: Boston-based visual artists Victoria DelValle and Ananda Toulon!

Visit our public art press mentions to watch the artists paint LIVE on CBS Boston with CRC and DCR. We had a lot of fun with WBZ-TV’s Levan Reid and crew at the skatepark (starting at 4:45am!).


Cambridge’s Riverbend Park is Now Open!

Opening day on April 2026!

It’s that time of year again! From the last Sunday of April through the second Sunday of November, a stretch of Memorial Drive in Cambridge is closed to vehicular traffic from 11am to 7pm, creating a large stretch of open space alongside the parklands to accommodate cycling, skating, running, and a range of other activities.

Due to ongoing construction associated with the Memorial Drive Greenway Improvements, Phase III project, Riverbend Park will be temporarily modified throughout the 2026 season. Learn more.


Season Opener: The Floating Wetland Returns!

Moving day success! On March 30, 2026, the Charles River Floating Wetland made its annual Spring journey from its winter berth at the MIT Sailing Pavilion back home for its 7th season (moseying downstream along a towpath that runs under the Longfellow “Salt and Pepper” Bridge). Come say hi to “FWed” and its usual spot near Broad Canal. Visit often to see its raft of native plants change colors and textures throughout the season, mirroring the change in trees and shrubs along the riverbanks. Island buds and blooms are soon to come, and you don’t want to miss them!

Don’t miss DCR’s social video spotlight on the Floating Wetland!


MWRA’s CSO Control Plan Still Releases Sewage in the Charles River During Heavy Storms: Public Comment Period Now Open

Get the full story on the Updated CSO Control Plan and learn how to take action on our Advocacy page.

Need a TL;DR on how the CSO plan is being presented and what’s at stake? Join Charles River Watershed Association (CRWA) and Mystic River Watershed Association (MyRWA) for Ending CSOs: The Time Is Now!, a webinar on the new draft Combined Sewer Overflow (CSO) long-term control plan. This webinar will summarize the plan and describe ways it can be much stronger at reducing sewage discharges, at minimal cost to ratepayers. There are two webinars (choose the one that fits your schedule best) on Tuesday June 9th (6:30pm) & Thursday June 25th (12pm), both virtually held over Zoom.

Public comments on the Draft Plan can be submitted to the project team through an online comment portal, by email (UpdatedCSOControlPlan@aecom.com), or by mail through September 30, 2026.

Worth reading: The Boston Globe (May 12, 2026) publishes “New plan would dump sewage into the Charles River for decades to come“.

The sewage is not just a problem for Boston-area residents. These outflows take place in more than 100 locations across the state, disproportionately impacting lower-income communities. In Lowell and Springfield, more than 400 million gallons of this toxic mixture are discharged into rivers every year on average, according to data compiled by the Massachusetts Rivers Alliance, a nonprofit conservation organization. “Combined sewer overflows are a statewide challenge, from the Pioneer Valley to Buzzards Bay,” said David McGlinchey, the alliance’s executive director.

Get ready for the biggest event of the Summer: City Splash 2026!! City Splash is a community event that provides the public the rare opportunity to swim in the Charles River and raise awareness to bring river swimming back to Boston! This annual state-sanctioned swim, hosted by the Charles River Conservancy, allows the public to experience the joy of swimming in the Charles River—one of the cleanest urban rivers in the United States! This year’s City Splash will be held on Saturday July 18th, so save the date to not miss out on your chance to swim!

Eager to splash with us? Subscribe to our e-news (link in bio) to be notified when swim registration goes live. Available swimming slots are capped to ensure a safe and fun event, and the demand to swim the Charles is HIGH and spots go FAST! 

Although all who swim must be pre-registered and be at least 18 years old, on-land activities on the @esplanadeinboston are free, all-ages, and open to the public throughout the event.

Swimming in the Charles River is only allowed if a permit is obtained from the Massachusetts Department of Conservation and Recreation (@massdcr) and we work in partnership with DCR to obtain a Special Use Permit for this unique event. The CRC has a vision for a swimmable river, but does not encourage swimming in the Charles outside of permitted events.

The Charles River Conservancy regrets to share that we have made the difficult decision to cancel the Skatepark Event, “Double Take, Skate Paint Imaginate”, this Saturday. The event is cancelled due to the Massachusetts wind advisory in effect this Saturday. The advisory notes unsafe conditions for engagement in outdoor locations. 

Everyone at the CRC wants to express our thanks to all of you who have shown up for the Lynch Family Skatepark Graffiti/Street Art Artist in Residence Program. From sharing our posts, to spreading the word, or cheering on members of the skatepark, it is an amazing display of community. We are excited to continue working with our 2026 Artists-in-Residence, Victoria (@thirteenvicarchive) and Ananda (@anandatoulon), on more events this Summer! 

Thank you for your understanding!
Join us at Lynch Family Skatepark THIS Saturday, May 30 from 12–4 PM for “Double Take: Skate, Paint, Imaginate,” a free, all-ages celebration of skate culture, live art, music, and community. 

Meet your 2026 Graffiti/Street Artists-in-Residence Victoria DelValle (@thirteenvicarchive) and Ananda Toulon (@anandatoulon), experience live painting in action, skate, connect, or simply come hang and enjoy the energy of the park. Coordinated alongside @childish.rayvino, the afternoon will feature live music from @lanz.la, @itsmizeyesis, @djlenore, and sound by @systemfailure617. Enjoy complimentary treats from @znzslushies_ and explore local vendors including @bruisedboutique, @scopeapparel, and @guerrilla.mag.

This residency marks the formal debut of Boston-based visual artists Victoria DelValle and Ananda Toulon’s collaborative practice as a duo. Together, they blend visual storytelling, spray-paint fluency, and community-centered artmaking to create work that evolves through dialogue, movement, and participation. Throughout the summer, their visual language of saturated color and surreal symbolism will transform the concrete pillars of Lynch Skatepark into a living canvas shaped by the rhythm and creativity of the space. 

So mark your calendars and join us THIS Saturday to celebrate the 2026 artists, skate culture, and our incredible @massdcr parks (especially Lynch!).

See you at the skatepark!! Bring your wheels and spray paint sets for the free walls!
