Geoscience Australia - National Surface Hydrology (Points) 2013

This dataset presents locations of national surface hydrological features in Australia as points at the 1:250,000 scale. \n\nThe following features are included in this dataset:\n\n * Bore - A small diameter hole in the ground for the purpose of obtaining subterranean water by natural flow or mechanical pumping.\n\n * 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.\n\n * 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.\n\n * 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.\n\n * 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.\n\n * Pool - A small body of still or standing water, permanent or temporary in an isolated natural depression, not within Watercourses.\n\n * Rockhole - A hole excavated in solid rock by water action. \n\n * Soak - A depression holding moisture after rain, especially the damp or swamp spots around the base of granite rocks.\n\n * Spring - A place where water issues from the ground naturally.\n\n * Waterfall Point - A sudden descent of water over a step or ledge in the bed of a watercourse.\n\n * Waterhole - A natural depression which holds perennial water, within a non-perennial watercourse or a non-perennial lake.\n\n * 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.\n\nFor more information please visit the [Geoscience Australia Web Service Portal](http://gaservices.ga.gov.au/).\n\nPlease note: \n\n * This dataset is a snapshot of Geoscience Australia's web service dataset as on 2019-03-12\n
