The most important lakes in the Faroe Islands are Sørvágsvatn on Vágar, Fjallavatn also on Vágar, Sandsvatn on Sandoy, Lake Eiði on Eysturoy and Lake Toftir on Eysturoy. There are many other smaller lakes across the whole country, most of them used for leisure fishing. Some of the lakes are also used for electricity production, and especially Lake Eiði near Eiði and the water systems around Vestmanna are important in this context. Also in Strond on Borðoy and at Botnur in Suðuroy there are important power-plants. The 10 largest lakes in the Faroe Islands (natural sizes) 1.
