Hydroelectric power is the electricity generated by the gravitational force of falling or flowing water through a turbine connected to a power generator. The three major types of hydropower facilities include reservoirs (high dams), in-stream (low dams), and pumped-storage. The most common type is the high dam, which creates significant reservoirs behind the dam (e.g., Hoover Dam). In 1882, the world’s first hydroelectric power station, located in Appleton, Wisconsin, produced 12.5 kilowatts of electrical power. Also in the early 1880s, a similar facility opened in New York City. Since these early facilities, hydroelectric power from the nation’s waterways has proliferated. Hydroelectric development in Arkansas can generally be grouped into three time periods—1924–1930; 1944–1973; and 1988–1999—and under three sponsoring agencies: Arkansas …
