The Umpqua River Light is a lighthouse on the Oregon Coast of the United States, located at the mouth of the Umpqua River on Winchester Bay, in Douglas County, Oregon.HistoryLocated at the mouth of Winchester Bay, Oregon, the first Umpqua River Light was built in 1855 and lit in 1857. Built along the river channel, the original light was vulnerable to seasonal flooding. This led to yearly erosion of the sand embankment of the light. In October 1863, the building's foundations had become too unstable and the structure soon collapsed. Before its collapse, the Light House Board had foreseen the need to build a new light at the location. However, it was 1888 before Congress approved of a construction of a new light.Construction started on the new light in 1892, and it was first lit in 1894. Built at the same time as Heceta Head Light, it was built from the same plans and is virtually identical to its more northern sister. Unlike its predecessor, the new light had several advantages over the original light. Built 100ft above the river, the new light was safe from flooding. This was partly due to the Light House Board's insistence that ships be able to plot a course based on visible lighthouses. The original light was not visible at sea and was only usable as an aid to ships approaching the river. The new light used a clockwork mechanism to rotate the Fresnel lens, and was eventually automated in 1966. The rotation mechanism served in the light for 89 years before it finally broke down and was removed. The Coast Guard, in charge of the light at this point, wanted to replace the mechanism with a new one. However, strong public outcry forced those plans to be aborted, and in 1985, the old mechanism was returned to its position after being fully restored.
