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.
Baillie-Grohman Canal The Baillie-Grohman Canal was a shipping canal between the headwaters of the Columbia River and the upper Kootenay River in the East Kootenay region of British Columbia at a place now known as Canal Flats, BC. The construction of the canal was required by the provincial government of British Columbia as a condition of the canal's promoter receiving substantial land concessions from the provincial government of British Columbia in the area of Creston, BC. The promoter, William Adolf Baillie-Grohman (1851–1921), was a wealthy adventurer, hunter author, and business promoter. He declared the canal to be complete in 1889. The canal was an expensive failure, being used only three times during its entire existence. In 1902, on the last use by a vessel, the sternwheeler "North Star", the sternwheeler's captain, Frank P. Armstrong deliberately blew out the canal's lower lock gates with dynamite to allow the transit of his vessel.
