History
The reservoir was constructed in three stages from 1969 to 1986 and has a capacity of about 32,000 ML.

The reservoir has a small natural catchment area, so to supplement its storage ability, two small diversion weirs and two tunnels from neighbouring catchments were built. These works and the subsequent raising of the reservoir embankment form the three main stages of the Merrimu Reservoir construction.

Purpose
The water in the reservoir is primarily used to supply drinking water to Melton and Bacchus Marsh with the remaining used for irrigation in the Werribee Irrigation District.

Merrimu Reservoir provides better management and regulation of water flows in the Werribee Basin, consequently increasing the security of supply to Werribee and Bacchus Marsh Irrigations Districts, urban and industrial supplies in the Melton and Bacchus Marsh areas.
