The incessant rains in Chennai over the weekend brought cheer to the city's water managers, as the storage in the four reservoirs went up.
The combined storage in the four reservoirs -- Poondi, Cholavaram, Redhills and Chembrambakkam -- stood at 4,091 million cubic feet (mcft), double the level it was on the same day in 2018, which was 1,694 mcft. The overall combined capacity is 11,257 mcft.
With forecast of more rains, the water managers are hopeful of a better situation next summer as Chennai witnessed one of its worst water crises this year following a weak monsoon in 2018.
In Erode district, a flood alert has been issued to people living on the banks of river Bhavani as a dam built across it was brimming in the wake of copious rains in catchment areas.

Consequently, Revenue officials released a flood alert and advised people living on the banks of River Bhavani to move to safer places.
