The Annual Report of the Commissioner of Lighthouses for the fiscal year ended June 30, 1920 notes that during the previous twelve months an acetylene light, consisting of a 200-millimeter AGA lantern and flasher mounted on a small lantern house had been established at Rubicon Point on Lake Tahoe at a cost of $1,352. The light was likely placed in operation in September 1919, as the Lighthouse Service Bulletin of October 1, 1919 noted that an acetylene light had been established at Rubicon Point. The light had a focal plane of 200 feet above the lake and produced a white flash every five seconds.
In 1921, the light on Rubicon Point was discontinued and moved four-and-a-half miles north to Sugar Pine Point where it was established on a square, pyramidal, wooden tower, which gave the light a focal plane of thirty-four feet above the lake. This change was noted in the Lighthouse Service Bulletin of November 1, 1921. The Coast Guard’s Light List for 1979 indicates Sugar Pine Point Light was still being displayed from a white tower, but its 1980 Light List indicates that a light atop a steel tower had taken the place of the wooden tower.
In 1929, the D.L. Bliss family donated 744 acres to the State of California, and D.L. Bliss State Park, which includes Rubicon Point Lighthouse was created. D.L. Bliss was a pioneering lumberman, railroad owner, and banker in the Lake Tahoe region. Renovation and stabilization of Rubicon Point Lighthouse was completed in 2001.
