By 2002, the St. Mary’s River Project (SMRP), led by St. Mary’s College of Maryland, had more than three years of water quality, land use, and biological data on the state of the St. Mary’s River. These data indicated that certain areas of the St. Mary’s River and its watershed were degraded. Yet, the SMRP framework lacked an avenue for community members to harness the data to promote sustainable land use planning, facilitate restoration efforts, or educate the community about the issues affecting the St. Mary’s River. Members of SMRP and the community gathered to fill this need, and the St. Mary’s River Watershed Association (SMRWA) was born.
In 2006, SMRWA received 501c3 status under the mission to "protect, improve, and promote the sustainability of the St. Mary's River Watershed through the collaborative efforts of economic, agricultural, environmental, social, cultural, and political stakeholders in the community." The St. Mary's River is used for numerous recreational and commercial activities, and we want to keep it swimmable and fishable for generations to come. To achieve this goal, our water must be clean, and the ecosystem must be healthy.
