By the mid-19th century, the city of Fall River had become a bustling textile-mill town, with regularly scheduled steamboat service to Providence, Rhode Island and New York City. The city is located at the mouth of the Taunton River where it meets Mount Hope Bay, which is an arm of Narragansett Bay.
Prior to the lighthouse, an unlit day beacon was constructed to mark the spot of a dangerous reef near the center of the relatively shallow Mount Hope Bay. In June 1880, $25,000 was appropriated for the construction of a new lighthouse on Borden Flats, which consisted of a 50-foot-tall (15 m) cast-iron tower that included a keeper's quarters. The light went into service on October 1, 1881, with a fourth-order Fresnel lens producing a fixed red light 47-foot (14 m) above mean high water. Rainwater was collected in gutters and stored in a cistern in the structure's basement level, providing the keeper's water supply.
The lighthouse, which sits in water open to the south, was battered in the hurricane of 1938. The storm left the structure with a pronounced tilt, which it still has. A new wider caisson was later added around the original one for additional protection.
In 1957 the lighthouse was electrified. It was automated in 1963. In 1977, its Fresnel lens was removed and replaced with a modern Vega VRB-25 lens. The fog bell remained in use until 1983 when it was replaced by an electronic foghorn. Under auspices of the National Historic Lighthouse Preservation Act of 2000, the lighthouse was auctioned privately through the General Services Administration. Nick Korstad, Cindy Korstad and Craig Korstad, of Portland, Oregon are the new owners. They have plans of fully restoring the light station and making it available for public tours and overnight accommodations.
