The reservoir was first constructed in between 1959 and 1961 and has the capacity of 8,600 megalitres (ML).
In 2002 major works were undertaken to bring the reservoir up to modern day standards, including anchoring the dam wall to the foundation bedrock and strengthening the four gates.
The dam is an essential part of providing water for cooling the power stations generators in the Latrobe Valley. This supply is supplemented from Blue Rock Lake approximately 15 km upstream on the Tanjil River.
