river is located in the Kelduhverfi County and is renowned for its
large sea trout and special ecology.
It discharges Lake Skjalftavatn, which was created during an
earthquake period in 1974.
Hot and warm springs in the river bed and the surroundings elevate the
water temperature to 10-12°C, which increases the growth of the trout
and makes the variety of other flora and fauna greater than in most
other such areas. Salmon
and sea char are also caught in the river and lake.
