The reservoir has a catchment area of 321 square kilometres (124 sq mi). The reservoir has a total capacity of 190,000 ML (42,000,000×10^3 imp gal; 50,000,000×10^3 US gal) of water; and covers an area of 3,290 ha (8,100 acres).[1][2] Southedge Dam has remained unused since it was opened in 1987;[3] constructed and owned by Southedge Pastoral Company.[4][5]
