The water measuring station of the Central Water Commission at zero point in Billsigundlu measured the inflow at 1,100 cusecs, against nearly 4,000 cusecs released from Karnataka. The inflow increased to 1,300 cusecs at 6 pm.

Officials said that it covered 2 km and reached Hogenakkal around noon. The PWD officials at Mettur expect it to reach the dam that is 53 km from Hogenakkal any time after 10 am on Saturday. At 8 am on Friday, water level in the dam stood at 20.25 feet against its height of 120 feet, with storage of 4.174 TMC against the full dam capacity of 93.5 TMC. 

The inflow at that time was 37 cusecs whereas the outflow was 500 cusecs. “Usually when the quantity of Cauvery water released from Karnataka is less, it reaches Mettur Dam 24 hours after crossing Billigundlu. But due to the drought the river bed is extremely dry, because of which we expect it to reach Mettur only around Saturday afternoon,” a senior PWD official said. 

Officials said that a host of factors decided the time taken for water from Karnataka reaching Mettur Dam. Stating that the distance between KSR and Mettur Dam is 182 km and the distance between Kabini and Mettur Dam is 241 km, officials said that only around 1,100 cusecs reached Billigundlu on Friday morning as the river was very dry in Karnataka too. 

While water released from those two dams is also used for irrigation downstream in that State and for meeting the drinking water requirements of Bengaluru. Sources said that when water released from the reservoirs in Karnataka is to the tune of 50,000 cusecs during floods water reached Mettur Dam much faster. 

“Inflow is good when it is more than 10,000 cusecs or more and it will reach Mettur in two to three days. We hope inflow will reach 1,500 cusecs to 2,000 cusecs at Billigundlu on Saturday and reflecting the increase in inflow at Mettur Dam on Sunday,” another official added.
