The reservoir has a capacity of 26,100 acre feet (32,200,000 m3) and a surface area of 953 acres (3.9 km²). The lake was formed in 1918 by damming Eleanor Creek as part of the Hetch Hetchy Reservoir system, constructed to supply water and power to the city of San Francisco.
Lake Eleanor is situated on the site of a smaller, natural lake of the same name. The lake was named after the daughter of Josiah Whitney, leader of the California Geological Survey in the 1860s.
The lake now provides opportunities for angling, hiking and camping.
