Reservoir levels are collected on a weekly basis covering Thursday to Wednesday each week. Data is uploaded to our website every Wednesday afternoon.

From 5 January 2017, past reservoir data for Toolondo Reservoir (since 2010) will be updated to reflect the most current bathymetric survey of the lake bed. This detailed survey indicated a greater depth in some parts of the lake than captured by prior reservoir capacity surveys. As a result, a greater volume will now be reported for Lake Toolondo, which recognises the volume in those deeper parts of the lake.
* Consists of storages at Mt Cole, Langi Ghiran and Olivers Gully
