Variables:

  • Site (the number of the data point itself)
  • RC (Regional Council that collected the measurement)
  • RCSiteID (the identifier used by that specific council)
  • SiteName (the Site where the measurement was collected)
  • DateChla (date the chlorophyll-a measurement was collected)
  • Year (Year of collection)
  • Month (Month of collection)
  • Chla ( mg chlorophyll-a per square meter)
  • NOxppb (Nitrous oxide parts per billion)
  • NH4ppb (Ammonia parts per billion)
  • DRPppb (Dissolved Reactive Phosphorus parts per billion)
  • TNppb (Total Nitrogen parts per billion)
  • TPppb (Total Phosphorus parts per billion)
  • DINppb (Dissolved Inorganic Nitrogen parts per billion)
  • EC (Electrical Conductivity)

TakeFrame dataset to accompany National water allocation statistics for environmental reporting; 2018 report.

www.mfe.govt.nz/publications/fresh-water/national-...

This report updates previously published statistics on water consented to be taken from surface and groundwater sources for consumptive uses (such as irrigation or drinking water). The report focusses on the potential pressure on surface water flows from consumptive water takes. Stream flow pressure is characterised by accumulating water consented to be taken as percentage of median flow in all river reaches affected by consented takes in New Zealand.

Data describing active consents.

  • AccumulatedFrame dataset to accompany National water allocation statistics for environmental reporting; 2018 report.

www.mfe.govt.nz/publications/fresh-water/national-...

This report updates previously published statistics on water consented to be taken from surface and groundwater sources for consumptive uses (such as irrigation or drinking water). The report focusses on the potential pressure on surface water flows from consumptive water takes. Stream flow pressure is characterised by accumulating water consented to be taken as percentage of median flow in all river reaches affected by consented takes in New Zealand.

Data relating to non-hydroelectric consents. It contains upstream accumulated maximum consented rates by use, source and in total. Please note that the upstream accumulated total for each nzsegment can appear in multiple rows; once for each FactorName.

This dataset was used for the "Consented freshwater takes" indicator, as part of the environmental reporting series: Our freshwater 2020. This indicator can be found at www.stats.govt.nz/indicators/consented-freshwater-...

  • This indicator helps us to understand where water is consented to be taken from, how much is allocated to be taken, and what it is used for. We report on the maximum volume that can be taken annually, and the maximum rate of take by primary use, primary source, and region for consents that involve consumptive water takes.
  • Our analysis and results have not included consents for hydroelectricity generation or non-consumptive water use. We also present the modelled potential impact of consented consumptive freshwater takes (excluding hydropower consents) on natural river flow across New Zealand.
  • More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.

This dataset reports modelled reference and current state of streambed deposited fine sediment at the REC1 stream segment scale. It provides predicted reference state from a boosted regression tree model trained on 1.) reference site data defined by land cover rules, 2.) all available deposited sediment. It also shows predicted current state trained on all available deposited sediment data.

See Clapcott & Goodwin (2017) for further information on the relevant model rules and data inputs.
