Aftermath

[edit]

Water levels on the Kelani River, which had peaked at 8 feet, began to fall slowly on 19 May 2016 and had fallen to six feet by 22 May 2016.[59][60] All schools in the country were closed on 20 May 2016.[61] Two people were killed in Ambulgama near Hanwella on 20 May 2016 after the boat they were in capsized in flood waters.[62] A landslide was reported in Kabaragalakanda near Aranayake on 21 May 2016.[63][64]

Prior to the floods Sri Lanka was suffering a drought and consequently power cuts as reservoirs ran dry.[65][66] Following the floods water levels in many of the reservoirs reached 75%, giving uninterrupted power supply according to the Ministry of Power and Energy.[67]

[edit]

The Sri Lanka Army deployed more than 1500 Army personnel and 71 officers, including Commandos in worst-affected areas across the country for immediate search, rescue and relief operations and the Army on the directions of the Commander has organized another emergency contingent to stand by in case the situation worsens.[78] The Sri Lanka Air Force dispatched Bell 212, Bell 412 and Mi 17 helicopters for rescue operations and providing of relief aid to victims.[79] The Sri Lanka Navy dispatched 81 flood relief teams in areas such as Thalduwa, Hanwella, Ranala, Navagamuwa, Malwana, Kegalle, Kaduwela, Mulleriyawa, Dompe, Pugoda, Wellampitiya, Kollonnawa, Biyagama, Kotikawatta, Angoda, Kelanimulla, Vavunia, Vilachchiya and Mandagalaru to promptly engage in any adverse situation.
