Signs of getting rains in the Cauvery basin have renewed with parts of Mandya district receiving showers on Thursday. The water level in the Cauvery basin reservoirs too has gone up, though not significantly.
Parts of Mandya, Ramanagaram and Mysuru districts received rains. Weather forecast by the Karnataka State Natural Disaster Monitoring Centre (KSNMDC) is that these districts may continue to get rains on Thursday night and Friday. This would help in increased baseline water flow to the Mettur dam in Tamil Nadu, they said.
The maximum rainfall recorded in Mandya district was at Nagamangala (46.5 mm), while it was Mayaganahalli which recorded the highest (21.5 mm) in Ramanagaram district. Rain was scattered in Mandya district. Intermittent rains are expected in Mysuru for the next couple of days. Kodagu started receiving rains on Thursday evening. The highest rainfall (14.5 mm) was recored at Bettadahalli in Somwarpet taluk.
Sources in the KSNMDC said that it is normal to get rains during the withdrawal phase of the south-west monsoon.
The combined water level in the four Cauvery basin dams in the state was 32.08 tmcft as on Thursday evening. It was 31.29 tmcft on Wednesday. On September 23, when the Karnataka legislature passed a resolution not to further release water to Tamil Nadu, the combined water level in the four dams was 27.6 tmcft.
The districts in the Cauvery delta region in Tamil Nadu are receiving good rains. Thiruvannamalai, on an average, received rainfall up to 90 mm, while Thiruvallur received 80 mm rain, the sources pointed out. The north-west monsoon is yet to begin in Tamil Nadu.
