River Eyjafjarðará has its source on the edge of the highlands south of Eyjafjörður and in the mountains around Eyjafjarðardalur. The river is a rain fed river with a 1300 sq.km catchment and flows through the valley about 70 km distance to the estuary in the Pollurinn near Akureyri. It is fishable for about 60 km, all the way to Brúsahvammur 450 meters above sea level. There are many tributaries that flow into Eyjafjarðará and all together they are fishable for about 24 km. In the upper beats of the river and many of the tributaries, char is dominant. Often, the first char are migrating around the middle of July, but the main migration is in the first part of August. A lot of immature char migrate into the lower beats in September. There are resident brown trout and sea trout in the lower beats, and they are often huge – up to 90 cm. The resident brown trout are caught all season but the sea trout are caught in the spring and in August and September.
