Service Description: Groundwater level data is collected by State and Territory water agencies and delivered to the Bureau in accordance with the Water Regulations. Selected further data is sourced outside for the Water Regulations, e.g. data supplied from National Collaborative Research Infrastructure Strategy (NCRIS).Groundwater level data in the Australian Groundwater Explorer is updated twice per financial year. The currency of the data varies per area and/or data provider.Groundwater level information can be presented using different terms or variables including:Depth to water (DTW)—measured from the ground surface to the groundwater level. Positive values are below the ground surface. Negative values are above the ground surface and indicate artesian conditions. This term is sometimes called depth below natural surface (DBNS).Standing water level (SWL)—measured from the reference point on the bore (e.g. the top of casing) to the groundwater level. Positive values are below the reference point and negative values are above the reference point.Reduced standing water level (RSWL)—the groundwater level elevation relative to the Australian Height Datum (AHD). This is the standard height datum used in Australia. It sets mean sea level as zero elevation. Positive values are above mean sea level and negative values are below.Information about groundwater level fields:HydroCode—Jurisdictional bore and pipe/outlet identifier (if relevant) e.g. GW030285.1.1 in NSW, 90001A in QLDAgency—Name of agency responsible for managing the bore e.g. Department for Environment and WaterWaterLevel—Availability of water level dataWaterCount—Number of water level measurementsWaterDateMin—Earliest date of water level dataWaterDateMax—Latest date of water level data

Subject: Groundwater levels and trends provide useful information about the availability of water resources, groundwater flow and the influence of factors, such as extraction and climate. Groundwater levels are measured in bores and reported as a depth or elevation. The Water level layer depicts bores with groundwater level data available through the Australian Groundwater Explorer. The colour of the layer represents the number of measurements on record, from dark blue (>200) to light blue (<5).
