Blue Rock Dam, Embankment dam near Moe, Victoria, Australia
Blue Rock Dam is an embankment dam on the Tanjil River in Victoria, forming a large reservoir used for both water supply and power generation. The dam wall stands 72 meters tall and runs about 600 meters across, holding back a body of water that covers roughly 873 hectares.
Work on the dam began in 1979 and was completed in 1984, built mainly to supply cooling water to the thermal power stations operating in the Latrobe Valley at the time. These stations were central to the region's energy production, and the dam was designed to support their ongoing operation.
The reservoir is a popular spot for fishing, with the Tanjil River feeding into it and offering good conditions for anglers. On weekends, families from nearby towns gather at the shoreline to picnic and spend time near the water.
The area around the reservoir has two separate recreation zones along the shoreline, each offering different activities such as walking trails and small motorboat access. Getting there early on weekends is a good idea, as parking can fill up quickly on fine days.
Although the dam was built for industrial water supply, it also generates around 9 gigawatt-hours of electricity per year through a small hydroelectric system integrated into the structure. Most visitors come for the recreation and never realize that the water flowing past them is also producing power.
