Pass Machac Light, Ponchatoula Louisiana
The Pass Manchac Lighthouse is the only lighthouse of its design in the Gulf Coast region.
Pass Manchac is a narrow neck of water. It connects Western Lake Pontchactiali to Lake Maurepes.
A lighthouse was authorized for $6,000 in 1834 and was completed in 1837.
This tower was rebuilt in 1846 and stood 32 feet high, elevating the lens 34 feet above sea level. The steady red light with nine lamps was visible for 13 miles. The first three lighthouses were built on the same general site. The first two were apparently brick towers. The third was a dwelling with a light centered on top.
The third lighthouse, begun in 1857, held its light 45 feet above sea level but was visible only 10 miles. The light was first exhibited in February 1859, with a Fourth Order lens. Built just before "the rebellion", the structure was heavily damaged by armies of both sides. The damage probably led to the building of the fourth and present Pass Manchac Lighthouse.
The Keeper's dwelling, which was attached to the light, was razed in 1952 and only the foundation remains.
The fourth tower is still active, although the original lens is no longer in use. A 250 mm plastic lens mounted on the lantern gallery and powered by batteries now guides shipping to the pass.
There are no other structures of its kind in the Eighth Coast Guard District. Most brick lighthouses have not survived, because the swampy soil common to the region would not support them. The Pass Manchac Light is one of only four that remain intact in Louisiana.
