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.NOTE: Whilst every effort has been taken in collecting, validating and providing the attached data, Melbourne Water Corporation makes no representations or guarantees as to the accuracy or completeness of this data.
