Amid the persisting flooding woes in the state, the Tirunelveli district administration on Saturday opened three sluices and released 1000 cubic feet of surplus water from Manimuthar Dam in Tirunelveli. The dam reached its full capacity last night, prompting authorities to drain water from the Manimuthar Dam into the Thamirabarani River. The total capacity of Manimuthar Dam in Tirunelveli is 5,511 million cubic feet while its maximum storage capacity is 118 feet.
