The main objective of this Nagarjuna Sagar project is to bring the 9 lakhs hectare of land under cultivation. The right canal was designed with carrying capacity of 11,000 Cusecs. The area irrigated by Nagarjuna Sagar Jawahar Canal is about 4.75 lakhs ha in Guntur and Prakasam districts (Anonymous, 1999). The Canal is divided into 9 branch canals spread across Guntur and Prakasam districts. The Right main canal having Guntur, Zulakallu, Bellarnkonda, Peddanandipadu, Addanki, Eddanapudi, Darsi, Pamidipadu and Ongole branch canals. International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 10 (2020) Journal homepage: http://www.ijcmas.com The Nagarjuna Sagar Project is one of the prestigious projects in India and it irrigates nearly 9 lakhs ha area .The canal is divided into 9 branch canals spread across Guntur and Prakasam districts. The month wise and branch wise discharge data and hydraulic particulars of main and branch canal was collected from Water Resources Department, Lingamguntla circle and Ongole circle. The daily rainfall data from 1997 to 2018 (22 years) obtained from the Directorate of Economics and Statistics (DES) was used for calculating annual availability of rainfall distribution over the command area. The total availability of the surface water of 11 years was is 2,229 MCM. Average annual rainfall of Guntur and Prakasam Districts under command area was noticed as 780 mm and 749 and overall command area was recorded as 765 mm. The average groundwater availability of the command area was estimated as 1385 MCM. Finally, conjunctive use of water in command area is 3,614 MCM (128 TMC).
