Layer containing line objects delineating hydrological features, representing waterways managed by Melbourne Water (i.e. catchment size is greater than 60 hectares) that have not been significantly modified by human activity. Captured by digitizing a line along the centre of a linear geographic feature. Includes the waterway name, a unique asset identifier, EPMS/asset section number (to link the object to associated drawings) and key attributes to assist with its intended purpose. When used in conjunction with the constructed waterways centreline and waterway connector centreline layers, this layer completes the waterway/hydrology linear network (complete centreline) for Melbourne Water’s non-underground drainage assets. Data set is used to indicate the location and types of natural waterways for asset management and maintenance works, to assess buildover or planning applications, for waterway rehabilitation works and flow management (helping maintain the flow of water and reduce the impacts of floods), ongoing condition monitoring and hydrologic modelling and analysis and to assist with the planning and design, construction of new waterway corridors, stormwater management (WSUD) options.Waterway (Reach) layer created 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.

Polygons showing the extent of wetlands in Victoria prior to European settlement. Includes all wetlands from Wetland_1788 and naturally occurring wetlands that were added to the updated current wetland extent (WETLAND_CURRENT). Where available original Corrick classification (primary categories based on water and salinity regimes) were retained. The polygon boundaries were derived from aerial photography interpretation. The most recent update to this database was in 2021.

Polygons showing the extent and types of wetlands in Victoria based on photography taken during the 1970's and 80's. Wetlands are classified into primary categories based on water regimes and subdivided into sub areas based on vegetation or hydologic attributes. The polygon boundaries were derived from digitizing marked up aerial photography interpretation.

This dataset is a copy of the WETLAND_CURRENT dataset prior to the 2025 update. Polygons showing the extent and types of wetlands in Victoria. WETLAND_CURRENT was created in 2013 and was derived from WETLAND_1994 (the state's first wetland geospatial inventory) and several local and regional wetland datasets. A number of updates have occurred to the dataset during 2014, 2017 and 2021. The 2014 update incorporated new regional mapping, some supplementary mapping and repositioning of planimetrically inaccurate wetlands. Supplementary mapping involved identifying and delineating wetlands which had not previously been mapped, but did not modify the extent of existing wetlands. It was undertaken primarily using aerial photograph interpretation (photos from 2007 to 2011) supplemented with existing geospatial datasets that provided context and informed the identification of wetland boundaries (e.g. vegetation mapping, topography). Wetlands were classified (according to the new classification framework) into primary categories based on wetland system type, salinity regime, water regime, water source, dominant vegetation and wetland origin. The 2017 update improved the accuracy of the layer by updating wetland mapping and attributes in the Melbourne area and for alpine bogs and fens in East and West Gippsland catchment regions. It also involved correcting inaccurate classification attributes and correcting wetland polygons for individual wetlands based on new data and feedback from wetland inventory users. The 2021 update incorporates new mapping and refinements to existing wetland polygons for several regional wetland datasets. These include Tootgarook Swamp, Alpine Bogs, Mitchell River Floodplain Wetlands, Melbourne Water Billabongs and Mallee CMA Wetlands. The dataset currently consists of 38,799 polygons totalling 784,120 ha.
