12 FOOTE : GEOLOGY OF THE BELLARY DISTRICT. 



1.330' above sea-level. 1 Six miles further north the river-bed at the 

 Moka ford has fallen nearly to 1,300'. 



The principal tributary of the Haggari is the Janagahalla, or 



Chinna Haggari, which drains all the southern part of the western 



half of the district. 



The Chikka Haggari The Chikka Haggari in the western part of 



the district offers no special feature of note. 



Of the minor streams tributary to the Tungabhadra, none is more

Minor streams tnbu- r "

draining the broad valley west of the Mallapan 



Betta hills ; the Hampasagara nallah ; the Hampapatana, or Balla- 



hunisi (Bullahoonshy) nallah, which drains the hilly country north of 



Kudligi, and the Gauripur nallah, which runs along the western base 



of the Raman Drug range. 



The Nari halla, which flows through the Sandur valley by the Ob- 



lagandi and Bhimagandi gorges, is a more im-

portant stream than any of the above three. 



After being dammed up to form the great Daroji Tank, it flows into 



the Tungabhadra by a nearly due northerly course. For its size it is 



a most useful stream, as it furnishes water for a great deal of 



irrigation along its banks. The two gorges by which it enters 



and leaves the Sandur State are very remarkable geological 



features. 



Eastward of the Haggari valley several large nallahs find their 



way down to the Tungabhadra, but none offer any points of 



special interest. They mostly flow through wide monotonous plains 



covered with cotton soil, and very few of them are utilized by the 



people for irrigation purposes, though many of them could be dammed 



back for the formation of tanks, if the people had a greater spice 



of energy in them. Only two need be named separately, the 



Harivanam nallah or Kariji Vanka, which is. of great size and drains 



1 I >342'33' minus the height of the bridge above the river-bed.
