Mount Hope Bay is a productive tidal estuary forming the northern arm of Narragansett Bay, straddling the border of Massachusetts and Rhode Island. It serves as the mouth of the Taunton River and connects to the Sakonnet River and the East Passage of Narragansett Bay. Historically impacted by industrial and sewage pollution, the bay has seen significant water quality improvements due to modern wastewater treatment efforts. This large, shallow bay system supports a diverse marine ecosystem and offers anglers a wide range of inshore and nearshore fishing opportunities from both boat and shore, with its health directly tied to the extensive Taunton River watershed.
