The Hálslón Reservoir (Icelandic pronunciation: [ˈhaulsˌlouːn] ⓘ) is a storage reservoir in Eastern Iceland on the Jökulsá á Dal River. The reservoir stores water for use in hydroelectricity production with the Kárahnjúkar Hydropower Plant. The reservoir was formed by three different concrete-faced, rock-filled embankment dams: the Kárahnjúkastífla Dam, the Desjarárstífla Dam [ˈtɛːsjarˌaurˌstipla] and the Sauðárdalsstífla Dam [ˈsœyːðˌaurˌtalsˌstipla].
