River Þverá is about 26 km long, from its source at Hámúlagarður in Fljótshlíð to the confluence of the River Eystri Rangá. It is rather small and neat to begin with but grows as tributaries join . It reaches about 4 cubic meters / sec at the confluence of Eystri Rangá. The fishing has been maintained with the release of about 20 thousand salmon smolts a year, which are released into 4 ponds by the river. Þverá has through the years given a remarkably good catch on the four rods, and the catch in 2020 was 675 salmon.
