Flókadalsá, often called Flóka, has the characteristics of both rain and spring fed rivers. It has its source from the west side of the glacier Ok and runs from there 35 km to Hvítá in Borgarfjörður, just above Svarthöfða. After a considerable fishway construction the river is accessible for salmon all the way to it’s source. Few rivers in Iceland have as constant water flow and little fluctuations in fishing as Flóka. Therefore, average catch is high considering the number of rods, and in 2008 and 2010 the river returned a catch of over 700 salmon. In the summer 2013 a record was made, when 937 salmon were caught. Licenses are popular, with the same people coming year after year.
