| History | | The reservoir's construction began in 1979 and was complete in 1984. It has a capacity of 208,000 megalitres (ML).
Following construction of the dam, the safe yield of the Latrobe River system upstream of the Morwell River Junction was increased to 325,000 megalitres per annum.
The embankment of the dam is constructed from earth and rock fill material.

| Purpose | | With its rich reserves of brown coal, the Latrobe Valley generates 85% of Victoria’s electrical power and continues to be a vital base for the State’s economic growth. To meet the planned industrial expansion in the region, an assured supply of water is essential to meet industrial, private irrigation and domestic water requirements.
The Latrobe Valley electricity generating companies are able to extract 150,000 megalitres per annum of yield from Blue Rock, for use as cooling water in existing power stations and for future power generation expansion.
Gippsland Water, which is the urban water authority for the Latrobe Valley, is able to draw 14,000 megalitres annually from Blue Rock to supplement Moondarra Reservoir.
Gippsland Water also pumps water from the Tanjil River to the township of Moe.
Water drawn from the storage is available to maintain minimum flows in the Latrobe River during periods of naturally low flows as required by the State Environment Protection Policy for the waters of the Latrobe River.
