Conimicut Lighthouse

Conimicut Lighthouse. . , Location: Conimicut Shoal, entrance to Providence River, Narragansett Bay , 41 43 01 N 71 20 42 W , Originally Established: 1868 , Present Light House Established: 1882 / Automated: 1963 , Construction Material: Cast iron / Present Optic: 250 mm, In November of 1868, the nearby Barrington Nyatt Point Lighthouse was discontinued and the original granite daymark in Conimicut was converted to a lighted aid. The new Conimicut Lighthouse did not provide a housing for the keepers, so the early keepers had to make a 1 mile rowboat trip from the former Nyatt Light to the new Conimicut Lighthouse. A five-room dwelling was built for the light keeper in 1874; but by the following March the house was destroyed by drifting ice., In 1882, the granite tower was replaced by a cast-iron lighthouse and was built upon a caisson sunken foundation that is 10 feet into the bay floor. The caisson was filled with concrete, but left space for a basement to provide storage for fuel and water. The lamp was a 10-sided lantern with a Fourth Order Fresnel Lens which was visible for 13 nautical miles. The lamp was 58 feet mean high water (highest average level water reaches on an outgoing tide). The new lighthouse also included a built-in housing unit underneath the light itself., In 1939 the U.S. Coast Guard assumed control of the nation's lighthouses, but it wasn't until the late 1950's that the actual operation of the lighthouse was transferred to the Coast Guard from civilian keepers. The upkeep of the lighthouse then fell under the jurisdiction of the City of Warwick., In 1960, the light was converted from a kerosene incandescent oil vapor lamp which required hand pumping to an electric lamp powered via a cable from the shore. This renovation made Conimicut Lighthouse one of the last lighthouses in the nation to be converted to electricity. Six years later, the light was automated and the resident keepers were no longer needed., In 2003, the light was converted to solar power. The former, but still operational, main power cable that runs under the shore line, is still in place., In 2005, the Conimicut Lighthouse Foundation was created to oversee the preservation of the Lighthouse. Later that year, a grant of $560,000 from the Department of Transportation was given to the foundation for the restoration of the lighthouse. The grant was purposed to restore the original appearance of the lighthouse and to recreate the keeper's residence., On September 29, 2004 a ceremony was held to announce the official change of ownership of the Conimicut Lighthouse to the City of Warwick under the National Historic Lighthouse Preservation Act through the efforts of Mayor Scott Avedisian and Councilman Joseph Solomon., Presently, a modern 250mm optic is in place and flashes every 2.5 seconds as an aid for boater navigation. A sensor at the nearby Warwick Light Station activates the automated horn during poor visibility., [Captions] , . (Left) The Fourth Order Fresnel lens.
