Layer containing water supply main centrelines for other authorities (assets not owned by Melbourne Water). This layer is generated from data received from other Water Authorities (Barwon Water, Gippsland Water, DELWP and other). This layer supports Melbourne Water to reference the existence and indicative location of water supply mains and their likely inter-connectivity with Melbourne Water assets. This layer is intended to be used for reference purpose only. Relevant authorities would need to be contacted if the data is to be used other than for reference.

This dataset provides daily measured streamflows into the four (4) major harvesting catchment dams in megalitres (ML). The streamflow is a calculated value which represents the observed 24-hour accumulated streamflow into the dam; net of any evaporation losses or rainfall gains from the dam surface. The streamflow measurement process requires reservior level, reservior gains and dam outflow data. The reservior level and dam outflow data is collected using telemetry devices. The reserviour levels are validated by Melbourne Water field operators. The dam outflow accounts for all water releases, including for consumption and for environmental purposes . The data is recorded at 8am daily. This data can be used in long and short-term catchment streamflow analysis.
