CWMA experts begin study of reservoirs in Cauvery basin


A three-week drive to study the performance of infrastructure facilities installed as well as to receive inputs on the storage/flows of all eight major reservoirs in the Cauvery basin commenced on Tuesday with experts from the Cauvery Water Management Authority (CWMA) of the Central Water Commission (CWC) visiting the Krishnaraja Sagar (KRS) reservoir in the district.

The team has representatives from Karnataka, Tamil Nadu, Kerala, and Puducherry. At least 20 officials/experts from the CWMA, officials from the India Meteorological Department, Department of Hydrology and some other departments began the exercise to receive inputs on the ‘telemetry-based real time data acquisition and transmission’ for online monitoring system for all the eight reservoirs.

The purpose of the visit is to conduct an effective study of the height of the reservoirs, efficiency of rain gauges and gauging stations, and receive inputs on the storage and inflow/outflow of the reservoirs, a member of the team said.

The official added that there are many radars, censors and gauging stations installed on the upstream and downstream of all the eight reservoirs.

The common purpose of radars, censors and gauging stations/centres is to measure the flows/storage by using innovative technology. Radars for the KRS are installed at Chunchanakatte in Mysuru district and Kollegal of Chamarajanagar district. The censors have been installed on the reservoir.

The team will gather information during the visit and share with the CWC to help the commission fix the quantum of waters to be discharged to the beneficiary States.

“We have already inspected KRS in the morning and will inspect the radar at Kollegal in the evening. We will continue the inspection at KRS on Wednesday too,” the official said.

The experts will inspect the Mettur reservoir, Lower Bhavani reservoir and Amaravathi reservoir from June 10 to 13. Inspections at Hemavathi dam in Hassan, Harangi in Kodagu, and Kabini in Mysuru districts will also be conducted before submitting a report to the CWC by the end of June.
