What Massachusetts Rivers Alliance does

Massachusetts Rivers Alliance (Mass Rivers) is a 501(c)(3) nonprofit advocacy organization founded in 2007 and headquartered in Somerville, Massachusetts, that operates as a coalition-based statewide voice dedicated exclusively to protecting the health of Massachusetts rivers. The organization convenes a coalition of more than 85 member organizations, including the Mystic River, Charles River, Merrimack River, Neponset River Watershed Associations and Connecticut River Conservancy, alongside individual supporters, and deploys that network through grassroots action alerts, legislative lobbying, public education campaigns, and direct engagement with Massachusetts state agencies and legislators. Mass Rivers focuses its advocacy on four policy areas: water quality, streamflow and drought management, wildlife habitat, and green infrastructure investment, and has translated that focus into measurable outcomes including passage of the Sewage Notification Bill (H.4921) in January 2021 and advocacy credited with over $40 million in increased annual state funding for environmental agencies such as MassDEP and the Division of Ecological Restoration since FY2020.

The organization delivers its work through a portfolio of advocacy programs and educational resources rather than technology products: the Dam Busters program targets dam removal and river restoration; Sewage Right to Know and Streamflow Protection campaigns drive legislative and regulatory change; the Stormwater Financing Toolkit, Rainwater Readiness Stormwater Series, and Advocacy Toolkit serve municipalities and advocates; and the Explore Your Rivers platform provides public-facing recreational information about Massachusetts waterways. Mass Rivers staff currently sit on over 30 state committees, commissions, and advisory groups, embedding the organization in policy development across water quality, drought response, climate resilience, and environmental justice.

Revenue is generated entirely through nonprofit channels, including individual charitable donations, organizational membership fees paid by watershed associations and partner nonprofits, and dedicated capital campaigns such as the Water Future Fund, which targets $1.3 million to fund the organization's 2025-2030 strategic roadmap with roughly $1 million committed from approximately 60 donors as of September 2025. The organization also pursues and supports increased state appropriations that benefit partner agencies. Operating with a small professional staff of fewer than 10 employees, Mass Rivers is currently transitioning executive leadership, with David McGlinchey succeeding Julia Blatt effective January 5, 2026, bringing prior experience leading government relations and policy at the Woodwell Climate Research Center. The organization is governed by an independent Board of Directors with no parent company or equity holders.
