Rising in the western hills of the Kalvan sub-division of Nasik, and fed by streams from the northern slopes of the Chandor or Saptashring range, after a course of about 150 miles, falls into the Tapti near Savda-Nanded. Its course lies in nearly equal parts in Nasik and Khandesh. Passing through Nasik almost in a straight line eastwards, in Khandesh its course changes to north-east, till, near Jalgaon, it bends north and then north-west flowing for several miles with many windings almost parallel to the Tapti. In Khandesh, except in one or two places where it is hemmed in by rocky hills, the Girna, over a broad sandy bed, flows through a well tilled valley gradually spreading into the great central plain. Its waters, both in Nasik and Khandesh, are much used for irrigation. In Nasik lately repaired dams and channels water many of its upland valleys, and in Khandesh, from Eahal about ten miles north of Chalisgaon, the Jamda canals stretch east for about twenty-seven miles on the left and twelve miles on the right bank.
