Water bodies in Godavari, Krishna basins present contrasting picture

At halfway through the current south-west monsoon season the water bodies in the two river basins in the State – Godavari and Krishna – are presenting a contrasting picture. While most of the major projects have received sizeable flood in the Krishna basin, many of the medium projects and minor irrigation tanks in the Godavari basin have received considerable inflows.

With the rains continuing to lash the catchment areas of Krishna and its tributaries Tungabhadra and Bhima in Karnataka, the prospects of major projects in the Krishna basin getting more flood have been boosted further. The Central Water Commission (CWC) has forecast huge inflows into Almatti, Narayanapur and Tungabhadra reservoirs, the three sources from which Srisailam and Nagarjunasagar get most of the water, for a few days more. According to a CWC advisory issued on Wednesday, the flood to Srisailam from Tungabhadra and Jurala is likely to increase further by Thursday night. The discharge of flood into the river course at Tungabhadra dam was about 1.90 lakh cusecs on Wednesday evening and it is likely go up further by Thursday night. Similarly, the discharge of flood from both Almatti and Narayanpur is expected to be in the range of one-lakh cusecs for a couple of days more.

Most of the medium irrigation projects and minor irrigation tanks in the Krishna basin are presenting a bleak picture with Dindi and Kotipally Vagu yet to get considerable flood as their storage stands about 25% of their capacity while Musi and Pakhala lake are half full. Wyra, Lankasagar and Bayyaram Tank, however, have received surplus inflows already, officials of the irrigation department stated.

The position of minor irrigation tanks is more pathetic with only 937 out of 14,956 minor irrigation tanks in the Krishna basin receiving water over 50% of their capacity including surplus in 119. Another 14,019 tanks have received less than 50% water of their capacity including 11,902 getting less than 25% water. Meanwhile, most of the major projects in the Godavari basin including Sriramsagar, Singur, Nizamsagar, Lower Manair and Mid Manair have received very small quantities of water compared to their capacity. The five reservoirs have received only 12.67 tmcft flood this season against their capacity of 188 tmcft. As on Wednesday, their combined storage stood at about 34.5 tmcft. But, projects such as Kaddam, Yellampally and Kinnerasani have received copious inflows and the authorities are letting out any major inflow, as it is coming.

The position of minor irrigation tanks in the basin, however, is presenting an encouraging picture with 13,770 out of a total of 28,869 tanks getting water more than 50% of their capacity including surplus water in 5,304. Another 15,099 tanks have received less than 50% of their capacity including 12,710 less than 25% water.
