In between Junction Canal and California Aqueduct which one was last used in 1871, and was then abandoned?
Junction Canal The Junction Canal was a canal in the states of New York and Pennsylvania in the United States. The canal was also called the Arnot Canal, after the name of its principal stockholder, John Arnot of Elmira, New York. The canal was built and operated by a private stock company. The canal was partly open in 1854, but the entire length was not finished until 1858. The completed canal was 18 mi long and had 11 locks. Then intent was to lengthen the reach of the Chemung Canal deeper into Pennsylvania in order to connect to the canal systems there. Competition with railroads led to diminished use of the canal. In 1865 the canal was severely damaged by a flood. In 1866, the stock company was authorized to change its name to the "Junction Canal and Railroad Company," and work commenced in constructing a railroad on its right of way. The canal was last used in 1871, and was then abandoned.
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.
