About Gundlakamma Reservoir
Kandula Obula Reddy Gundlakamma Reservoir Project is formed across the Gundlakamma river near Chinnamallavaram (Mallavaram) village in Maddipadu Mandal of Prakasam District. The Central Water Commission describes the Gundlakamma as an independent, east-flowing river and places the project site about 25 km from Ongole. Its reservoir is an irrigation and drinking-water source; it is not a developed tourist attraction, and the sources below describe it only as a water project.

Dam and spillway details
According to the Central Water Commission (CWC), the project consists of an earthen dam 5.630 km long and a 227 m long spillway with 15 vertical gates, built to store 3.859 TMC of water. The older figure of 5.699 km that appears in some listings differs from the CWC document, so this page uses the CWC figure.

Irrigation and drinking water
The CWC states that the project is meant to irrigate 25,250 hectares (62,394 acres) in kharif and 32,400 hectares (80,060 acres) in rabi, across 5 mandals of Prakasam district and 4 mandals of Bapatla district, and to add to drinking-water supply for about 2.5 lakh people in 43 villages along the canals and in Ongole town. The two canals together are proposed to serve an ayacut of 32,400 hectares (80,060 acres).
The Prakasam district website says the project was built across the river at Mallavaram, with the dam about 80 feet high and a storage capacity of 12.845 TMC, and that water was released from it in November 2008 by the late Chief Minister Dr. Y. S. Rajasekhara Reddy. The same page also mentions a high-level canal dug at the 22.5 m level from the rear end of the Right Main Canal, which was mostly complete with a small stretch pending litigation in the High Court of Andhra Pradesh.
