According to Nam Ha Tinh Irrigation One Member Co., Ltd., due to the influence of the tropical depression strengthening into storm No. 4, from the evening of September 18, there will be widespread moderate and heavy rain in Ha Tinh.
Heavy rain caused water levels in some lakes and dams to rise quite rapidly, including Kim Son Lake and Thuong Song Tri Lake in Ky Anh town.
To proactively respond to heavy rain forecast to last until September 21, Nam Ha Tinh Irrigation One Member Co., Ltd. will release overflow to regulate water in these two lakes from 8:00 a.m. on September 20.
Kim Son Lake is overflowing with an expected flow rate of 5 - 50 m3/s; Thuong Song Tri Lake is overflowing with an expected flow rate of 10 - 100 m3/s.
The spillway discharge to Kim Son Lake and Thuong Song Tri Lake is to ensure safety for the project and downstream areas. The completion time is based on weather conditions and lake water levels.
Nam Ha Tinh Irrigation Company Limited requests the People's Committee of Ky Anh district, Ky Anh town and affected communes in the system to urgently notify, urge and guide people to implement measures to ensure safety for people and property.
From 5:00 p.m. on September 19, Ho Ho Hydropower Plant (Huong Khe) also regulated the spillway. The regulated flow is announced to range from about 50m3/s to 800m3/s depending on the water flow into the lake at different times.
