Across the Livanjsko field flow several rivers, which belong to the Adriatic watershed. The most important of these are the Žabljak, the Sturba, the Bistrica, the Brina, the Plovuča, the Jaruga and the Ričina which are all rich in trout and crab. An artificial lake, Buško Blato, was dammed in the polje in the 1970s for electric power generation. Additional projects are in planning which could seriously compromise the delicate hydrological balance of the Dinaric karst, which is criss-crossed by underground rivers.
