At the time of its inauguration in 2008, only 15,000 acres out of the total envisaged area of 80,000 could be irrigated due to issues in land acquisition for constructing canals.[4][5] As of 2024[update] land acquisition issues continue to dog the project preventing full utilisation, as some of the affected farmers did not agree to the compensation fixed by the government.
Design
It is planned to use 12.845 TMC of water through filling the reservoir 6 times during the monsoon season to provide irrigation facilities to 62,368 acres in Khariff and 80,060 acres in Rabi seasons in 6 mandals of Prasakam district. It is also planned to provide drinking water facility to 2.56 lakh population in 43 villages enroute canals and to Ongole town.
The reservoir consists of earthen dam with a length of 5.699 km, 227 meters long spillway with 15 vertical gates. The crest level of gates is +16.38 M for a maximum flood discharge of 2,72,000 cusecs. Right canal with take off at 3.785 Km of right bund for a length of 27.26 Km feeds an ayacut of 28,000 acres. Left canal with take off at 0.9 Km of left bund for a length of 21.975 km feeds an ayacut of 52,060 acres.[1]
Land acquisition issues
Maintenance
Two crest gates of the reservoir developed leaks in 2023, leading to loss of water and also damage to ayacut crops, as water was released suddenly to manage the crisis.[7]
