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.

This data provides daily accumulated water usage volumes supplied from the 10 Melbourne Water storages. This data is collected using more than 120 Flow Monitoring devices across Melbourne Water's Water Transfer Pipe Network, linked to the Telemetry System. Melbourne Water collects and stores observations at six minute intervals. This data summarises the usage volume supplied by Melbourne Water over a 24 hour period (8am to 8am). Water recipients include 3 metro water retailer companies and 5 regional water authorities. This data set is best used in long and short term water demand analysis.

Daily observed Storage Dam Volumes at 10 Water Storage Dams operated by Melbourne Water. This data is collected with telemetry devices installed at the storage dams, and verified with field observations. The storage volume is recorded at 8:00 am daily. This data is best used in long term storage volume analysis.

Daily point rainfall values. This data is collected with rainfall telemetry devices installed at the catchment storage dams, and verified with field observations daily. This data provides daily rainfall observed for the 24hr period from 8am to 8am. This data provides our customers and community with the daily observed rainfall information. This data is best used in long term rainfall analysis at the four major melbourne storage dams (Maroondah; O'Shannassy; Thomson; and Upper Yarra). This dataset is not suitable for event modelling which requires higher frequency observations.

This data provides daily accumulated inflow volumes for wastewater treatment at the two Melbourne Water site (Western and Eastern). This data is collected using network flow monitoring devices. This data has been processed and stored as official inflow volumes received by Melbourne Water over a 24 hour period (12am to 12am). Wastewater volume is the total accumulated flow received from the sewer and stormwater networks. This data set is best used in long and short term wastewater services demand analysis.

Layer containing water supply storage dams (location and extent). These are major water supply system storages. Captured using as-constructed drawings and aerial imagery, and includes storage dam name, category / type, asset identifier, as=-constructed plan references plus other key attributes. This layer is intended to be used to locate and obtain details on Melbourne Water's water supply transfer assets for asset management, buildover (Dial-Before-You-Dig) and operational or maintenance purposes. This layer is updated when new information is received from completed projects and/or updated from certified survey plans. Melbourne Water are responsible for reviewing and accepting information which results in update to the existing layer.

This data contains points representing drain and waterway outlet locations, associated with a natural waterway or channel centreline, within the Greater Melbourne region. This region includes the Port Phillip Bay and Western Port coastlines. Points are captured to show the indicative location of the endpoint for a waterway or channel as geographic coordinates. The data table includes minimal attributes to assist in identifying the feature. Data was created using the waterway (Reach) layer from original FIS 1:50K (Vicmap Hydro) streams data set, which included only those waterways within catchments of greater than 60ha. Waterways (Reach) Rectification project undertaken 2001 to 2003 to review and correct the extent of the waterways reach network to ensure a complete data set exists (using the Drainage Metropolis Boundary, 50K data, 1:2500 Drainage Record Plans, Drainage Limits data, orthophotos, as constructed and/or design drawings, contour data and Melway Street Directory). Waterway (Reach) extents defined and attributes populated in GIS and AMIS for all records including assigning nodes and node numbers (for start / end points) and removing any reaches less than 100 metres in length that are predominantly channel assets. Waterways in extended area incorporated in 2005 using Vicmap Hydro data and aerial imagery, then updated in 2009/10 using Lidar survey data (contours). Data is maintained using Lidar survey data (contours) and 60 ha limits. Please refer to metadata for each dataset row record for specific source / accuracy information.
