The availability of water played an important role in the growth of Columbus. The city constructed its first dam in 1908, and later completed a second in 1925. The two dams supplied enough water for one half million people, which was twice the cities population. In 1955 the city had outgrown its capacity and it experience a severe drought. The city then built Hoover Dam on Big Walnut Creek. Only 10 years later, the city was in need of an additional water supply. A large underground water supply between Big Walnut Creek and the Scioto River was discovered. Wells were dug and they now supply 20 million gallons of water daily to residents.
