Storage Levels

All Reservoirs overview

South Gippsland Water operates four reservoir-fed networks across our region to supply potable water to our larger population centres. These graphs present our storage levels across our reservoir supply systems. Values represent the average for the month.

We also operate five river-fed supply systems, drawing from the Tarwin, Agnes, Tarra and Tidal Rivers, which do not have large off-stream storages. Instead water is drawn directly from the river for treatment at the relevant Water Treatment Plant before the water is supplied to customers in the townships.

Lance Creek overview

Lance Creek Reservoir is South Gippsland Water's largest, supplying to several towns, which make up over 50% of our service area's population.
First constructed in 1911, further works were made in 1985, increasing to today's capacity of 4,200 megalitres.

Additionally, the Lance Creek network is supplemented by the Melbourne Water Supply Grid, including the Victorian Desalination Plant in Wonthaggi.

Leongatha overview

The Ruby Creek water supply system consists of four reservoirs in Fairbank. These reservoirs collectively supply Leongatha Water Treatment Plant, which manages potable water for Leongatha and Koonwarra.

Beginning with Reservoir No 1 constructed in 1906, capacity was further increased with the additions of Reservoir No 2 in 1928, Hyland/No 3 in 1960, and Western/No 4 in 1981.

Battery Creek overview

Battery Creek Reservoir is South Gippsland Water's smallest, and supplies the small township of Fish Creek to its north. It was constructed in 1960.

Deep Creek overview

The Deep Creek water supply system provides potable water for the town of Foster.

Foster Dam, constructed in 1997, holds the majority of storage for the network with a capacity of 201 megalitres. The original Deep Creek Reservoir, constructed in 1940, and raw water basin at Foster Water Treatment Plant provide the remainder of capacity.
