The fishing area Efri Brú is probably the best in Lake Úlfljótsvatn. There is a considerable current in the channel between Flatey and Kvíaness, which often holds huge Arcic char and very good brown trout. It is good to use a large strike indicator and a very long leader and upstream the channel with heavy nymphs. Before the days of the power plants, there was a waterfall with a drop of about a meter. It was considered a spawning ground for brown trout in the autumn.
