Chennai: Shutters of all the four drinking water storage reservoirs near the city had to be opened on Saturday due to heavy inflows.

The Sathyamurthi Sagar dam in Poondi received 32,100 cusecs inflow and 35,118 cusecs were released. The surplus water flows through the Kosasthalaiyar river, which has a flood carrying capacity of 1.2 lakh cusecs.

About 6,600 cusecs, which was the rate of inflow, was discharged from the Red Hills reservoir.
