In 2001, the MyRWA entered into an agreement with Tufts University to house its records at Digital Collections and Archives within Tufts and make them available to researchers. The MyRWA and Tufts are actively involved in the Mystic Watershed Collaborative, whose goal is to develop greater awareness and understanding of important environmental problems in our bioregion that affect human health and quality of life.

The Mystic River Watershed Association was founded in 1970 to protect, restore and conserve Mystic-area waters. In the 1990s, the Association's charter was changed to include local groups as well as individual members. In late 1997, MyRWA became a leading force in the formation of an independent watershed-wide coalition of citizens' groups

The MyRWA records cover a wide range of material of interest to Watershed residents, researchers, historians, and others. They cover topics directly related to the watershed, such as runoff and eutrophication, as well as topics of more general relevance, such as traffic and bird watching. Of particular interest is the extensive selection of documents pertaining to the construction of the Alewife MBTA station in the 1980s. One particularly notable feature of the collection is that it contains reports, correspondence, articles, brochures, legal documents and maps created not only by the MyRWA but also by related organizations, such as the Environmental Protection Agency and the Joint Regional Transit Committee.

A complete list of the records available to researchers is available from the Tufts Digital Library.
