After the Ia Ring reservoir (Chu Se district, Gia Lai province) leaked at the dam body, a working group from the Ministry of Agriculture and Rural Development went to the scene to inspect and determine the cause in order to have a solution.
On the morning of November 15, Mr. Nguyen Anh Tu, Deputy Head of Dam Safety Department (Department of Irrigation - Ministry of Agriculture and Rural Development) and industry experts were present at Ia Rin reservoir (Chu Se district, Gia Lai province).
Here, experts directly entered the sewer tunnel area to examine the current situation, find out the cause of the incident in order to develop a solution.
At the scene, about 6 square meters of the upstream dam roof next to the bottom discharge culvert that collapsed has been sealed. The water level in the lake is lower than the landslide location, the incident is temporarily under control.
With the treatment measures of boulders, stone baskets, sandbags, tarpaulins and spillways to lower the water level, the amount of water flowing through the main water intake corridor and draining downstream has been reduced to about 0.5 m3/s.
Speaking to VietNamNet, Mr. Vu Ngoc An, Deputy Director of the Department of Agriculture and Rural Development of Gia Lai province, said that as of 11:30 p.m. on November 14, the authorities were still mobilizing human resources, materials, machinery and equipment to handle the incident. As of 5 a.m. on November 15, the water level of Ia Ring Lake was 685.80m, of which the spillway elevation was 684m.
According to Mr. An, to continue serving the inspection and troubleshooting work, up to now, the operating unit continues to spill with a flow rate of 30 m3/s to lower the water level, and is expected to bring the water level back to the overflow threshold this afternoon.
The Deputy Director of the Department of Agriculture and Rural Development of Gia Lai province added that during the process of regulating the spillway discharge, depending on the actual situation, Gia Lai Irrigation Works Exploitation Company Limited will adjust the appropriate discharge flow, continue to monitor the lake water level and check, fix problems, and implement solutions to ensure the safety of the project.
Regarding the damage, Mr. An said that currently all forces are focusing on overcoming the incident to ensure the safety of the project, so the damage has not been estimated yet.

As VietNamNet reported, at around 3am on November 14, the dam body of the Ia Ring reservoir leaked water and collapsed about 6m2, causing water to flow into the culvert corridor and then downstream.
Immediately afterwards, the departments, branches and Chu Se district arrived at the scene, directing the authorities of neighboring communes to urgently mobilize forces and vehicles to the rescue. Along with troubleshooting, the authorities opened the spillway gates to lower the water level to reduce pressure on the dam body.
