The bill titled "An Act designating the Marion Stoddart riverwalk" seeks to officially designate the accessible trail along the Oxbow of the Nashua River in the J. Harry Rich State Forest, located in the Town of Groton, as the Marion Stoddart Riverwalk. This designation honors Marion Stoddart for her significant contributions to the restoration of the Nashua River, her role in the passage of the Massachusetts Clean Waters Act, her founding of the Nashua River Watershed Association, and her efforts in promoting community-driven conservation education.

To implement this designation, the bill mandates that the Department of Conservation and Recreation erect suitable markers that comply with departmental standards. The bill emphasizes the importance of recognizing Stoddart's legacy in environmental conservation and aims to inspire future generations to protect the river and its ecosystems.
