Taking farmers’ concerns into account, authorities are exploring ways to fix the damaged crest gate no. 19 of the Tungabhadra reservoir, which was washed away late on Saturday after its chain link was broken, keeping the water loss to the least possible quantum.
The government is consulting a second team of experts to explore how this can be done, after the first team held that the reservoir had to be emptied by half before a new gate could be fixed.
As much as 35,000 cusecs of water began gushing through the damaged gate as soon as the link broke. Authorities then raised the remaining 32 gates to increase the spillway discharge to reduce the pressure on the damaged gate.
Technical experts, who rushed to the reservoir on Sunday, initially held that installing a new crest gate in place of the damaged one would be possible only after half of the water in the reservoir was drained.
Accordingly, the spillway discharge was further increased to one lakh cusecs on Sunday and 1.4 lakh cusecs by Monday morning. The increased spillway discharge triggered panic among farmers in the command area that spreads across Karnataka, Andhra Pradesh, and Telangana.
However on Monday, Koppal district In-charge Minister Shivaraj Tangadagi said that efforts were on to fix the problem without draining the reservoir.
“One team of technical experts thinks that the new gate could be installed only after emptying the reservoir by half. Considering the farmers’ concerns, Chief Minister Siddaramaiah directed us to explore other possibilities to fix the issue without draining the reservoir. So we have today engaged another team of experts from JSW in Toranagallu, Ballari district. The team has started work,” Mr. Tangadagi said.
