Australian Hydrological Geospatial Fabric - Water Bodies

﻿ Abstract Waterbodies are bodies of fresh water with potential significance for water balance and water reporting purposes. Composited from AusHydro V2, waterbodies comprise three major categories - * Lakes: A naturally occurring body of mainly static water surrounded by land. * Reservoirs: A body of water collected and stored behind a constructed barrier for some specific use (with the exception of Flood Irrigation Storage). * Swamp (subset of AusHydro feature class "Flats"): Land which is so saturated with water that it is not suitable for agricultural or pastoral use and presents a barrier to free passage or Low lying land usually adjacent to lakes or watercourses, which is regularly covered with flood water for short periods. These features represent waterbodies that are related to the stream networks by storing the HydroID of the most downstream outlet JunctionNode. These features will also contain MappedArtificialFlowSegment. A subset of the water bodies within the AHGFWaterBody Feature Class are associated with the Bureau’s [Water Storage Product] and are attributed by SLAKE_Name, SLAKE_Syst and SLAKE_URN. For further information on how to link the Water Storage features in the Geofabric to the Bureau’s Water Storage Website, refer to the tutorial [Access Water Storage information].

More information can be found at the [Geofabric Documentation] page. Lineage statement The Geofabric is an ongoing project which is the result of considerable effort and consultation by several agencies, both within Australia and internationally. The project is being led by the Bureau of Meteorology, in partnership with Geoscience Australia (GA), the Australian National University Fenner School of Environment and Society (ANU) and CSIRO Land and Water Flagship (CSIRO). The dataset presented here is a subset extracted from the national Geofabric Version 3.3 dataset. This dataset has been re-projected from GDA94 to Web Mercator as part of the Digital Atlas of Austalia project. Minor changes to symbology have been performed only as neccessary to meet the requirements of this project.
