The "Somasila Dam" is a dam constructed across the Penna River near Somasila, Nellore district, Andhra Pradesh, India. The reservoir impounded by the dam has a surface area of 212.28 km2 (52,456 acres) with live storage capacity of 1.994 km3 (1,616,562 acre⋅ft) or 75 tmcft.[2]
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.
