Chief Minister Y.S. Rajasekhar Reddy assured that the government would modernise the Krishna western delta region at a cost of Rs 5,000 crore to prevent floods, which every year, causes havoc in the eastern parts of Prakasam district. He revealed that the design of the Krishna western delta was planned 150 years ago by Sir Arthur Cotton and emphasised the need to modernise it. The Chief Minister visited the town on Thursday, and inspected flood-affected areas near Chirala and Karamchedu mandals.
