Maranoa-Balonne-Condamine surfacewater EC sites

## **Abstract** \n\nThis data and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nThe DNRM Water Measurement Information System Extract contains data collected from the State's Stream Gauging Station Network. This also includes an extract of water quality information. Refer to WMDP_UG_102014.pdf for the list of stream gauging stations managed by the Department of Natural Resources and Mines.\n\n## **Dataset History** \n\nThe department operates the Stream Gauging Station Network primarily to fulfil legislative requirements under Part 3, s35 of the Water Act 2000 (Qld) to regularly measure and keep publicly available records of volume and quality of water in Queensland.\n\n\n\nThe network assesses the state's water resource availability by providing data for hydrologic analysis, operation and management activities to ensure the productive and responsible use of natural resources. The network also provides real time information to the Bureau of Meteorology to assist with flood forecasting services which are used by local authorities across Queensland to prepare for potential flood inundation.\n\n\n\nThe Stream Gauging Station Network consists of around 400 stream gauging stations across Queensland that collect height and flow information. In addition, around 170 of these sites also collect time series water quality information. The network is operated by departmental Hydrographic staff within an ISO 9001:2008 accredited quality management system. Stream flow measurements are an integral part of the production of volumetric data for stream gauging stations throughout Queensland. Hydrographic staff take measurements throughout the full range of low and flood flow conditions.\n\n\n\n\n\nGaps in data records\n\nGaps in data records are more to occur likely during extreme events, particularly for TSWQ stations, where the data is automatically audited and potentially erroneous data is prevented from being displayed (Unreported data).\n\n\n\n\n\nData validation\n\nDNRM is endeavouring to validate data as quickly as possible. Our performance indicator aims for data to be validated is within 160 days. You may wish to request updated information periodically to be supplied with the current validated data.\n\n\n\nWith respect to use of data: \n\nUnvalidated data (Quality Code 130) has not been rigorously assessed and the data is quality coded to indentify this. These data should by used with care as they may change after validation. These data should only be used by persons who are familiar with the characteristics of streamflow information.\n\nValidated data are data that has been assessed and is the best available quality at the time, however the data should always be interpreted taking into account the quality codes that have been applied.\n\nHydrologic advice should be sought to assist with any interpretation.\n\n\n\n\n\nWater monitoring sites\n\nPlease see How water is monitored for further information on the departments water quality and quantity monitoring networks.\n\n\n\n\n\nCurrent TS and water quality data Quality Codes\n\nThe Quality Codes the department currently uses are listed in the table below. These may be seen when viewing recent data.\n\n\n\nDescription Print Quality Code Quality Code Height (m) Flow Rain (mm) EC (S/cm) Temp (C) PH DO (mg/L) \n\nGood 10 \n\nWater level below threshold (no flow) B 15 \n\nFair 20 \n\nPoor 30 \n\nEstimate E 60 \n\nInterim 130 \n\n\n\n applies to time series data type\n\n\n\nPrint Quality Code reflects the numerical Quality Code on pre-computed outputs \n\n\n\n\n\nAll current and historic data Quality Codes\n\nThe complete list of all current and historical Quality Codes are shown in the table below. Historical codes are indicated in italics and may be seen when viewing historical data, DNRM does not employ them in routine operations.\n\n\n\nDescription Print Quality Code Quality Code \n\nGood (Actual reading) 1 \n\nHistorical data code 9 \n\nGood 10 \n\nWater level below threshold (no flow) B 15 \n\nFair 20 \n\nGood daily records (BoM data) 26 \n\nPoor 30 \n\nGauging temp - Good 31 \n\nGauging temp - Fair 32 \n\nGauging temp - Poor 33 \n\nGauging temp - Composite 34 \n\nGauging temp - Suspect instrument 35 \n\nGauging temp - Derived measurement 36 \n\nGauging temp - Discharge correlated 37 \n\nGauging temp - Data of no value 39 \n\nDerived height (CITEC data) \\* 59 \n\nEstimate E 60 \n\nDerived discharge \\* 69 \n\nBack water affected (CITEC data) 79 \n\nAccumulated rainfall (BoM data) 80 \n\nWet days within period 81 \n\nRainfall (non-standard) 83 \n\nGauge height > instrument threshold 119 \n\nHistoric water quality data, Fair 125 \n\nNot coded (unvalidated data) \\* 130 \n\nInterim I 140 \n\nUnknown quality U 150 \n\nUnreported data Blank value field 151\n\n160\n\n170\n\n180\n\n200\n\n201\n\n255 \n\n\n\nItalics applies to historically used data QualityCodes\n\nPrint Quality Code reflects the numerical Quality Code on pre-computed outputs\n\n## **Dataset Citation** \n\nQueensland Department of Natural Resources and Mines (2015) Maranoa-Balonne-Condamine surfacewater EC sites.
