Lake Svínavatn in A-Húnavatnssýsla is a popular fishing lake. It is about 12 km² in area, at 123 m above sea level and its maximum depth is 38 m. The lake is part of the river Láxá in Ásum water system and a reservoir for Laxárvirkjun. There are two species of char in the lake and one species can grow very large, up to 13 lbs, but they are mostly caught in nets rather than on rods. The weight of the largest trout is very similar. The other char species are rather small and are usually caught on a rod. The best angling opportunities are on the south side of the lake and by the so-called Klappir in the land of Mosfell.
