The dam's purpose includes environmental flows, hydro-electric power generation, irrigation, and water supply.

Commenced in 1964 and completed in 1976, the Brogo Dam is a major dam on the Brogo River, a tributary of the Bega River, and is located approximately 30 kilometres (19 mi) northwest of Bega.

Dairy farming is the main industry in the Bega Valley and the dam ensures a continuous and reliable supply for this activity.

The uncontrolled unlined rock cut spillway is capable of discharging 3,700 cubic metres per second (130,000 cu ft/s).

The area surrounding the dam has abundant ferns and rock orchids that provide a photographer's paradise.
