According to Tri An Hydropower Company, at 4:00 p.m. on October 18, the lake's water level was 61.3 m and the water flow through the spillway was 160 m3/s.
Tri An Hydropower Company will stop discharging water through the spillway at 8:00 a.m. on October 19.
Depending on the weather, water flow to the lake, water level of Tri An Hydropower Reservoir, water level downstream of the river at Bien Hoa hydrological station, the company can regulate the discharge of water through the spillway.
Previously, in September 2024, when Tri An hydroelectric reservoir closed the spillway, hundreds of people in Dong Nai and Ho Chi Minh City brought many types of fishing gear such as fishing nets, boats, buoys... to the foot of the spillway to catch fish.
According to local residents, when Tri An Hydropower Reservoir released floodwaters, fish followed the water to the foot of the spillway. When the dam is closed and the flood discharge is stopped, the water will recede, causing fish to get stuck under the spillway area and people can easily catch fish with a "huge" size and weight, up to more than 10kg.
The types of fish that people catch include many types such as silver carp, giant catfish, yellow catfish, red-tailed catfish, silver carp, black carp...
After that, people sold fish right at the foot of the dam, many people earned millions of dong.
Tri An Hydropower Plant has 4 generators, with a total designed capacity of 400MW. This is the largest hydropower project in the Southern region, contributing greatly to the national grid, helping to regulate domestic and production water sources, push salinity and regulate floods in downstream areas.
