In Iran, the mugger occurs along rivers in Sistan and Baluchestan Provinces along the Iran–Pakistan border. A population of around 200 mugger crocodiles lives on the Iranian Makran coast near Chabahar.

Following several tropical cyclones in 2007 and 2010, much of the habitat of the mugger crocodiles has been restored as formerly dry lakes and hamuns were flooded again. In Pakistan, a small population lives in 21 ponds around Dasht River; in the winter of 2007–08, 99 individuals were counted. By 2017, the population had declined to 25 individuals.
