The 1946 Biennial Report of the Nevada State Engineer states that B. F. Porter Estate was using Crowbar Spring for stock watering. The estate was also using water from Chipmunk Spring, Johnstone Spring and Whiterock Spring.
The name "Crowbar Spring" appears in the 1979 1:24,000 map by the same name.
