Inscription. Diversion Dam was completed in 1909 to lift water into an already constructed New York canal system, greatly expanding its irrigated farmlands.

After a quarter century of failure to dig a large canal above Diversion Dam, United States Reclamation Service funding enabled a group of Boise Valley irrigation districts to complete this project. Then in 1912, a generating plant was installed to provide power to construct Arrowrock Dam. It has been preserved as an historical display by Bureau of Reclamation staff.
