This water area is in Aðalvík and the estuary and a large part of the lake belongs to the deserted farm Stakkadalur. Stakkadalsvatn is 5 m above sea level and its area is about 0.29 km². Into it flow the rivers Stakkadalsá and Reyðardalsá and a small river from Torfavatn. The whole lake area has sea-run char, sea trout and occasional salmon that are caught in the estuary. Fishing can be good, especially in the estuary. There is also good fishing in the rivers, mainly for sea-run char that are commonly two to three pounds. The number of sea trout has increased, but there are not many salmon. The best chance is in a fishing spot in the estuary called Skjónuhylur. Landowners have exercised their fishing rights, but anyone who requests it is allowed to fish in the water area.
