In 1947, talks were initiated between Finland and the Soviet Union concerning the regulation of Lake Enare. During the 1950s, relations progressed between Norway and the Soviets concerning the development of the common border river, and an agreement was reached in 1958. Altogether there are seven power plants along the stretch between Enare and Bøkfjorden, and the three southernmost are on Russian territory, all of them built during the 1950s. On the border river between Norway and Russia there are four power plants. Two are owned by Russia, Hestefoss (1970) and Boris Gleb (1963). Two of them, Skogfoss (1964) and Melkefoss (1978), are owned by Norway. Of these four, Hestefoss occupies the highest position on the watercourse (the furthest south) and Boris Gelb the lowest, not far from the outlet of the River Pasvik in Bøkfjorden. The two Norwegian power plants are situated between the two Russian ones.

There has been organized collaboration between Norway, Russia and Finland concerning the regulation and manœuvring of Lake Enare and the other storage facilities in the watercourse since 1959. There are regular meetings between the three responsible parties to discuss and agree their usage. Norway and Russia have power interests, while Finland has the greatest interest in avoiding flooding during periods of overflow.
