February 1973 until 3 July same year.

Three watersheds are clustered together on the north-
eastern flank of Vatnajökull: Hálslón, Ufsarlón, and Hraunaveita, while Blönduvirkjun
extends between Langjökull and Hofsjökull.
The hydropower catchments vary in size, ranging from about 130 km2 (Hraunaveita) to almost
1,800 km2 (Hálslón), and two of them have a mean elevation above 1,000 meters (Hágöngulón
and Hálslón). Only Búðarháls has
