The reservoir can get water by gravity from the Srisailam reservoir located in Krishna basin. It is the biggest storage reservoir in Penna River basin and can store all the inflows from its catchment area in a normal year. This reservoir can also feed by gravity nearby 72 tmcft gross storage capacity Kandaleru reservoir. Under Indian Rivers Inter-link projects, it is planned to connect the reservoir with the Nagarjunasagar reservoir to augment its water inflows.[citation needed]
