Expected spillway of Buon Kuop and Serepok 3 hydropower reservoirs

Buon Kuop Hydropower Company has issued the first warning of overflow at Buon Kuop and Serepok 3 hydropower reservoirs.

In recent times, moderate to heavy rains have occurred in the basins of Buôn Tua Srah, Buôn Kuốp and Srêpok 3 reservoirs over a wide area, leading to a significant increase in water flow to the reservoirs. Currently, the water levels of the reservoirs are higher than or approximately equal to the highest water levels before the flood (the time of implementing the Operation Procedures for reservoirs and inter-reservoirs during the flood season).

These two reservoirs have small capacities (daily regulation), currently the flow to the reservoirs is smaller than the flow running the machines, however due to technical constraints on the power system, the National Power System and Electricity Market Operation Company (NSMO) does not exploit/does not exploit the maximum of the Buôn Kuốp and Srêpok 3 generators, so the water levels of the reservoirs are increasing significantly.

According to the forecast of the National Center for Hydro-Meteorological Forecasting, in the coming days, the Central Highlands and the South will have scattered showers and thunderstorms, locally heavy rain, with rainfall of 10 - 30 mm, locally over 50 mm. In addition, the low pressure area in the northeastern sea of ​​the North East Sea has strengthened into a tropical depression.

Buon Kuop Hydroelectric Reservoir is expected to have to spill over in the coming days.

Based on the current hydrological developments and the exploitation situation of the reservoirs, in the coming time, the Buôn Kuốp and Srêpốk 3 reservoirs are at risk of having to discharge water through the spillway for the first time to ensure that the reservoir water level complies with the regulations in the reservoir and inter-reservoir operation procedures. For the Buôn Tua Srah reservoir, due to the low reservoir water level and large flood prevention capacity, there will be no need to discharge water through the spillway during this rainy season.

In order to ensure safety for the project and downstream areas, comply with the reservoir and inter-reservoir operation procedures, Buon Kuop Hydropower Company requests the Steering Committee for Natural Disaster Prevention and Search and Rescue, departments, branches and local authorities to direct and disseminate to people in the downstream areas of Buon Kuop and Serepok 3 reservoirs about the above spillway regulation risks so that they can know and proactively prevent them. Thereby, harvest agricultural products, aquatic products and crops; do not leave agricultural tools in low-lying areas and flood drainage areas along the river.

For tourism exploitation units (Dray Nur waterfall and Dray Sap waterfall), always monitor the weather situation and information on the operation of Buon Kuop reservoir to proactively prevent, especially when the reservoir overflows; tourism exploitation activities along the river of Dray Nur waterfall must fully comply with the committed contents.

Buon Kuop Hydropower Company will regularly monitor weather developments in the basin. When regulating through reservoir spillways, it will implement information and notification regimes according to regulations.
