Usta (Norway)

Usta or Usteåne is a river located in the municipality of Hol in Buskerud, Norway.

It flows from Lake Ustevatn traveling northeast down the valley of Ustedalen to its confluence with Holselva.

The ski resort at Geilo is situated just north of the river, about halfway down Ustedalen valley.

The valley stretches about 20 kilometres (12 mi) east from Ustevatn and meetings Holsdalføret below Hagafoss.

The power station uses the fall in the river Usta of 540 metres (1,770 ft) from Ustevatn and Rødungen.
