In between Junction Canal and California Aqueduct which one was last used in 1871, and was then abandoned?
California Aqueduct The Governor Edmund G. Brown California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern and Central California to Southern California. Named after California Governor Edmund Gerald "Pat" Brown Sr., the over 400 mi aqueduct is the principal feature of the California State Water Project.
Eureka station The Eureka Valley Station was an underground streetcar station in San Francisco, California, in use from 1918 until 1972. It was located inside the Twin Peaks Tunnel, very close to its eastern end, in the Eureka Valley neighborhood. Its location was chosen with the intent that it could serve as a transfer station to the Sunset Tunnel, whose east portal in early plans was to be located at the corner of Market and Eureka streets.
