Haukadalsvatn is 3.28 km², 41 m deep and 37 m above sea level. There is a good population of Arctic char in the lake and sometimes salmon are also caught, as the salmon river Haukadalsá flows through it. The size of the char caught is 1-2 pounds, mostly caught on worms, flies, or spinners. The best fishing is usually where streams flow into the lake. Haukadalsvatn is a late summer lake and therefore the best fishing time is from mid-July until the end of September.
