This stretch of the Žabljak, like all rivers in the southeastern half of Livanjsko Polje, is regulated. For 3.8 kilometers from its wellspring to the bridge on highway Livno-Split (M107/M16), where remains of an old bridge called Rimski Most (literally English: Roman Bridge) can also be found, the Žabljak runs unregulated, and from the bridge to its confluence with Bistrica, 2.8 kilometers, the riverbed is regulated.
