The Freshwater Project - The springs of the Gacka River

Gacka is a river located in the Lika region in central Croatia. Because for a large part of its course it is a subterranean river, estimates on its length vary. The overground part has undergone substantial human intervention - before it was 32 kilometers long, now it is only 11 km. It has been regulated by man to flow into an aquaduct in Gusic´ polje (known as Tunel Gacka-Gusic´ Jezero and then into the Adriatic Sea through a hydroelectric installation HE Senj near Sveti Juraj. HE Senj takes inflow from Gacka and Lika, since it was built in 1965. The river passes through karst fields and most notably the town Otocac, and its headwaters are known as a superb spot for trout fishing.
