 The Mashkel River crosses the Siahan Range at Tank-e-Zurrati and runs along the western side of Kharan to the Hamun-i-Mashkel, the total length from the source of the Rakshan being 258 miles.Through a considerable water course, the banks of the Rakshan are low, shelving and irregular, consisting of hard clay known as kork in the Balochi language.The river carries high floods, but owing to its breadth they never do much harm.
