Thac Mo Lake was formed between 1991 and 1995 with the construction of the Thac Mo Hydropower Plant dam on the Be River. The plant, with an installed capacity of 150 MW, was one of the early major hydropower projects in southeastern Vietnam and created a reservoir of about 109 sq km for power generation, flood control and irrigation.

The lake is an important livelihood area for local communities, supporting fishing, aquaculture and agriculture. It is a well-known local recreation area for residents of Phuoc Long and Dong Xoai and is often visited during festivals and weekends for boating and lakeside gatherings.
