devoted to the design of multiple arch dams. Multiple arch dams In the early 20th century, Salt Lake City regularly experienced severe water shortages in mid-winter and late summer. To alleviate this, bonds were floated in 1914 to finance the construction of three storage dams, the largest being Mountain Dell Dam in Parley's Canyon, ten miles east of the city, that was built in two stages from 1914 to 1925. Earlier, Eastwood had built four dams in California and his reputation as dam designer was growing. He had written several articles in Western Engineering describing his Big Bear Valley Dam, Los Verjeles Dam (in Yuba County, California) and Kennedy Dam (in Jackson, California), and had also published a four-page promotional "supplement" distribution with copies of the March 1915 Western Engineering. Following the initial construction of Mountain Dell Dam, Eastwood continued his career in water resource development and dam design, becoming involved in projects in California, Idaho, Arizona, Mexico, and British Columbia. He was not an armchair engineer, and he spent much of his life in the field working on practical problems of water control. He worked as a practicing engineer until the end of his life, when, in August 1924, at the age of 67, he drowned while swimming in the Kings River east of Fresno. He was buried in Mountain View Cemetery near Fresno, a cemetery that he had surveyed and laid out during his time as Fresno's first City Engineer. The Eastwood powerhouse at Shaver Lake, California was named after him. Built in 1987, the 200 MW pumped storage hydroelectric plant is located underground and was carved out of solid granite. Work Throughout his career, Eastwood designed a total of 17 dams: one in Utah, one in Arizona, one in British Columbia, and two in Idaho, with the remaining 12 located in California. His notable projects include: Hume Lake Dam, Fresno County, California (1908) Big Bear Lake Dam, Big Bear, California (1912) Mountain Dell Dam, Salt Lake County, Utah (1914-1925) Lake Hodges Dam, Escondido, California (1918) Fish Creek Dam, Carey, Idaho (1919) Anyox Hydroelectric Dam, Anyox, British Columbia (early 1920s) Cave Creek Dam, Maricopa County, Arizona (1923) Little Rock Dam, Littlerock, California (1924) Florence Lake Dam (1926) References External links Biography from the Water Resources Collections and Archives, University of California, Riverside Historical Accounts of the Central Sierra Building the Ultimate Dam: John S.
