Who invented reservoirs?

Why were dams built in the past?
Initially, dams were built for providing a lasting supply of water for human use as well as for irrigation. Over the years, dams were built for other aligned objectives like flood control, navigation, maintaining water quality, generating hydroelectricity etc.
