Cramer Reservoir, though USGS maps misspell it as Craemer, is located a short distance to the southwest side of Horse Lake. Charles Cramer came to Lassen County in 1864. In time, Cramer would assemble several large ranches in Lassen County. On September 5, 1874 Cramer purchased 160 acres at Horse Lake from Joe Hale, co-owner of Susanville’s Pioneer Saloon, for $600 and would continue to acquire more property there. On May 21, 1900, his son, Daniel F. Cramer obtained the rights to construct the reservoir. On July 18, 1939 the Cramer family transferred the Horse Lake property to California Lands Incorporated.
