The longitude and latitude of this project are 79° 42’€™30″€ and 15° 02’€™ 30″€. The catchment area of this project is 2202 Sqkm, reservoir capacity is 1105.328 Mcft (31.30 MCum). The proposed utilization of this project is 2000 Mcft. The ayacut contemplated under this project is 16000 Acres. The left canal is of 2.8Km length & irrigates 1500 Acres ayacut. The right main canal is for a length of 20.14Km & it irrigates 14,500 Acres ayacut. There is an old spillway with 10No’€™s vertical gates with size 12.19 X4.57 M. There is a new spillway with 5 Nos radial gates of size12.19X7.62 M. The TBL & FRL of project is +45.415 M & +41.15 M respectively.
The mandals benefitted out of this project are Kondapur mandal of Nellore district, Lingasamudram & Guduluru Mandals of Prakasam district. The Assembly Constituency of this project is Kandukur.
