believe it or not there is much, much bigger problem with that watershed ... it is a disused gold mine Stolice, which has a huge reservoir of toxic sludge (cyanide, arsen, mercury) deteriorating and threatening to burst into the drina river (upstream to danube and shit lot of people, mind you).

we are talking about hundreds of tons of stuff and nobody gives a shit as the last owner of the mine was some kind of political figure (reads : war profiteer turned politician). and even if a good fairy was to appear and cough out the dough to fix it all i still doubt it would be fixed, instead local trash would find a way to misappropriate funds, not giving two fucks what happens tomorrow.

look for "people are tribal" amos's monologue from SF book "the expanse" if you wonder "how come" while reading this...
