Stephens Creek Reservoir is an artificial dam situated 17 km north east of the far western town of Broken Hill, New South Wales, Australia.
It was originally built in 1892 by the Broken Hill Water Supply Company to hold 20,000 megalitres of water and to provide a continuing water source for drought-ridden Broken Hill. The reservoir soon became inadequate and a further reservoir, Umberumberka, was built to add to the water supply. Stephens Creek Reservoir remains the primary water source for Broken Hill, a city of around 20,000 people and is a popular picnic area.
