Lake Berufjarðarvatn is rather small or 0.15 km² in area, rather shallow on the west side but more depth is to the east. The lake is 49 m above sea level and has a maximum depth of just over 2 m. The lake is about 600 m long and about 300 m where it is widest. Alifiskalækur flows into the lake, with Kinnastaðaá flowing out of it and then to Þorskafjörður. There are a lot of fish in the lake, usually weighing from 1 – 3 pounds. Brown trout is the main catch, with some char. The largest weighed fish ever caught in Berufjarðarvatn on a rod was about 10 pounds in weight. People usually enjoy fishing the lake, as the fish bite well and usually no one goes home without a fish. There is good fishing all season, all day, but the better fishing is in the first part of the summer. And as elsewhere, the mornings and evenings give the best fishing.
