Description: All best available features have been included from the Surface_HydroPoints_National data capture. 250K Specification Description -
Bore - A small diameter hole in the ground for the purpose of obtaining subterranean water by natural flow or mechanical pumping.
Dam - An open body of water collected and stored behind a constructed barrier consisting of earth, rock, concrete and/or masonry. Generally designed to capture run-off from the surrounding landscape or rainfall. The storage of water may occur on or below ground level.
Lock - An enclosure in a water body with gates at both ends to raise or lower the water level to enable vessels to pass from one level to another
Gnamma Hole - Small holes of varying shape, diameter and depth, found in hard granite outcrops and in the decomposed granite of a breakaway, which can and usually does hold water.
Native Well - An isolated natural depression which holds water, not within Watercourses. The natural phenomena is sometimes improved by indigenous persons for their own water collection purposes.
Pool - A small body of still or standing water, permanent or temporary in an isolated natural depression, not within Watercourses.
Rockhole - A hole excavated in solid rock by water action.
Soak - A depression holding moisture after rain, especially the damp or swamp spots around the base of granite rocks.
Spring - A place where water issues from the ground naturally.
Waterfall Point - A sudden descent of water over a step or ledge in the bed of a watercourse.
Waterhole - A natural depression which holds perennial water, within a non-perennial watercourse or a non-perennial lake.
Water Tank - Water Tanks are storage containers for water, usually used for human consumption and other purposes such as irrigation, agriculture, fire suppression, agricultural farming and livestock, chemical manufacturing and food preparation. Water Tanks are constructed of various materials including plastic (polyethylene or polypropylene), fiberglass, reinforced concrete, steel (welded or bolted, carbon or stainless). Those used for human consumption are generally fully enclosed.

Description: All best available features have been included from the Surface_HydroLines_National data capture. 250K Specification Description -
Canal Line - An artificial open channel which provides the supply, distribution or removal of water for irrigation purposes, or for a significant infrastructure function (such as salt interception, land reclamation, or drainage between water features for environmental management purposes).
Rapid Line - An area of broken, fast flowing water in a watercourse, where the slope of the bed increases (but without a prominent break of slope which might result in a waterfall), or where a gently dipping bar of harder rock outcrops.
Water pipeline - A hollow cylinder of variable dimension used for carrying water.
Watercourse - A natural channel along which water may flow from time to time. Connector - An artificial line used to connect linear Hydrographic features across a defined area feature to allow network analysis of riverine networks. Connections across area features will be defined by the visual interpretation of imagery to achieve logical water flow patterns based on subtle variations in soil, vegetation and noticeable landform slope.

Description: All best available features have been included from the Surface_HydroPolys_National data capture. 250K Specification Description - Lake - A naturally occurring body of mainly static water surrounded by land. (Source - http://www.ga.gov.au/mapspecs/topographic/v6/appendixA_files/Waterbodies.html). NOTE - This layer only displays 1:300,000 to 1:9,000 to avoid clutter at the national scale (approx 1:36,000,000). Refer to other Waterbody - Lake layers at different scales for the National Map.

Canal Area - An artificial open channel which provides the supply, distribution or removal of water for irrigation purposes, or for a significant infrastructure function (such as salt interception, land reclamation, or drainage between water features for environmental management purposes).
Estuary - The part of the mouth or lower course of a river in which its current meets the sea's tides, and is subject to their effects.
Swimming Pool - An artificial body of water intended for swimming or water-based recreation, situated either above or in-ground.
Flood Irrigation Storage - A body of water collected and stored behind constructed barriers, for the specific use of flooding pastures via internal irrigation systems.
Town Water Storage - A body of water collected and stored behind a constructed barrier for some specific use (with the exception of Flood Irrigation Storage). Town Water Storage are bodies of water primarily stored for the consumption of urban, semi urban and rural township populations. The water is treated post storage by government, or private authorities, and connected to government regulated water networks.
Rural Water Storage - A body of water collected and stored behind a constructed barrier for some specific use. Rural Water Storage are bodies of water stored for rural farming and agricultural practices (with the exception of Flood Irrigation Storage) and/or for the consumption of the associated land owners. The water is not treated by government authorities or connected to government regulated water networks.
Lake - A naturally occurring body of mainly static water surrounded by land.
Watercourse Area - A natural channel along which water may flow from time to time.
Aquaculture Area - Shallow beds, usually segmented by constructed walls, for the use of aquaculture.
Salt Evaporator - A flat area, usually segmented, used for the commercial production of salt by evaporation.
Settling Pond - Shallow beds, usually segmented by constructed walls, for the treatment of sewage or other wastes.
Swamp - Land which is so saturated with water that it is not suitable for agricultural or pastoral use and presents a barrier to free passage.
Marine Swamp - That low lying part of the backshore area of tidal waters, usually immediately behind saline coastal flat, which maintains a high salt water content, and is covered with characteristic thick grasses and reed growths.
Foreshore Flat - That part of the seabed or estuarine areas, between mean high water and the line of lowest astronomical tide.
Saline Coastal Flat - That nearly level tract of land between mean high water and the line of the highest astronomical tide.
Land Subject to Inundation - Low lying land usually adjacent to lakes or watercourses, which is regularly covered with flood water for short periods.

Description: The basins and catchments are part of the National Catchment Boundaries dataset which was developed by Australian National University (ANU) using the 9 second Digital Elevation Model and streams from GEODATA 1:250k data produced by Geoscience Australia. It represents the drainage areas from a pre-European landscape. The dataset was created to support the Australian Hydrological Geospatial Framework (Geofabric) released by Bureau of Meteorology with collaboration with ANU, CSIRO and Geoscience Australia.
