Tri An Lake

Tri An Lake is a large artificial reservoir on the Dong Nai River in Vinh Cuu District, Dong Nai Province, about 30 km northeast of Bien Hoa. Created by the Tri An Hydropower Dam constructed between 1984 and 1991, it covers approximately 323 square kilometres. The lake is notable for its expansive water surface, scattered forested islands, hydroelectric function, and role in fishing, irrigation and emerging eco-tourism in southern Vietnam.

Visitors can expect a vast freshwater reservoir surrounded by forested hills and small islands, with calm waters used for fishing and boating. The lakeside offers viewpoints of the dam, boat piers, floating fishing villages, and forested islets accessible by hired boat. The setting is rural and tranquil, with opportunities for photography, lakeside camping, cycling along embankment roads, and observing daily life of local fishing communities.

Formed by the construction of the Tri An Hydropower Plant between 1984 and 1991 with assistance from the Soviet Union. Upon completion it was the largest hydropower station in southern Vietnam, built to generate electricity, regulate floods and provide irrigation water for the Dong Nai River basin.

The lake supports livelihoods of fishing and aquaculture communities in Vinh Cuu and surrounding districts and serves as a popular weekend recreation area for residents of Dong Nai and Ho Chi Minh City, with lakeside gatherings and boat-based visits to forested islands.
