HydroFrame 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.

HydroFrame contains consumptive hydropower information.

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.

The “Consented freshwater takes” indicator uses two datasets

• Consented_freshwater_takes_accumulated_frame. The original dataset on MfE data service is data.mfe.govt.nz/table/102976-national-water-alloc...
• Consented_freshwater_takes_take_frame. The original dataset on MfE data service is data.mfe.govt.nz/table/102978-national-water-alloc...

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.

“RemovedTakeFrame” has a similar format to “TakeFrame”, but “RemovedTakeFrame” contains data for consents whose rates of take were either all missing or all zeros

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.

This indicator measures the average percentage of streambed covered by fine sediment for areas of smooth, unbroken water in hard-bottomed, wadeable streams and rivers, at 215 sites across six regions assessed at least bi-monthly for two consecutive years between 2014 and 2019.

Summary report available at www.mfe.govt.nz/publications/fresh-water/indicator....

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 indicator reports on six measures of lake water quality based on spatially modelled data for:

• chlorophyll-a
• total nitrogen
• ammoniacal nitrogen
• total phosphorus
• water clarity
• trophic level index (TLI3).

​

For these measures we report on:

• modelled median values for the period 2013–17
• for selected measures, how these values compare to the National Objectives Framework (NOF) bands related to ecosystem health (MfE, 2017).

​

This indicator includes spatial predictions for 3,802 of 3,820 lakes in New Zealand (majority of New Zealand lakes that are larger than 1 hectare), based on measurements at 61–104 lake sites (the number of sites differs by measure).

HydroAccumlatedFrame 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: a) the influence of all non-hydroelectric consents; b) the influence all consumptive hydroelectric consents; and c) the combined influence of all consumptive consents, regardless of hydroelectric or non-hydroelectric. Please note that the upstream accumulated total for each nzsegment can appear in multiple rows; once for each FactorName.

We report on the conservation status and most recent change in status of indigenous (native), resident (breeds in New Zealand) freshwater fish and invertebrates that have been assessed by New Zealand Threat Classification System (NZTCS) expert panels.

This indicator measures the physical habitat condition of New Zealand waterways. We report on 369 sites across six North Island regions and 90 sites in one South Island region (Southland), identifying the overall state of stream habitat at each site based on at least three years of data between 2013/14 and 2018/19. Ten physical habitat components are measured during the assessment, including bank erosion and the diversity and abundance of fish cover (Clapcott et al, 2019).
