Water release from Poondi reservoir, a major source of supply for Chenai, was reduced on Saturday as there was a dip in the inflow from catchment areas in the region.
As of now, water is being conserved in various other reservoirs instead of being let into the sea, according to Water Resources Department officials.
After nearly five days, the department reduced water discharge to 500 cusecs from 1,000 cusecs earlier.
