Dầu Tiếng Reservoir

Dầu Tiếng Reservoir is a reservoir located among three provinces / muninicpality of Tây Ninh province, Hồ Chí Minh City (Bình Dương province previously), and Đồng Nai province (previous Bình Phước province previously) in the Southeast region of Vietnam. The lake was formed by damming the upper reaches of the Saigon River, making it the largest irrigation reservoir in Vietnam and Southeast Asia. Construction of the lake began in 1981 after surveys were conducted starting in 1976. The project was completed with over 100 million USD in funding, which the Vietnamese government borrowed from the World Bank, making it the first project in Vietnam to be built using US dollars since the Reunification of Vietnam on April 30, 1975.

Before construction, the lake's development sparked considerable debate among the leaders of Tây Ninh province regarding the choice of the lake's name and the project's feasibility. Nevertheless, the construction proceeded. Since 2017, Dầu Tiếng Reservoir has been classified as a project of national security importance due to concerns that a dam breach would affect the Ho Chi Minh City metropolitan area. As of 2022, Dầu Tiếng Reservoir is managed by the Southern Irrigation Exploitation One Member Limited Liability Company under the management of the Ministry of Agriculture and Rural Development.

In 2005, along with Black Virgin Mountain, Dầu Tiếng Reservoir was selected to appear in the central part of the logo of Tây Ninh province.
