This dataset was first added to MfE Data Service on 20 Sep 2019.
This dataset shows land that would be covered by the option 1 of section 8.4 Immediate action to reduce nitrogen loss.
This web map has been developed by the Ministry for the Environment to support policy proposals in the Action for Healthy Waterways discussion document. The proposals are currently being consulted on.
It provides extra detail on Option 1 in section 8.4 of the discussion document (Immediate action to reduce nitrogen loss). The map indicates the pastoral catchments and sub-catchments specified as high-nitrate in Option 1, where regional rules are not already in place or proposed, and shows the land considered to be low-slope.
Low-slope is defined in this option as land parcels with an average slope of less than 5, 7 or 10 degrees. We are seeking feedback on the appropriate slope threshold to use.
The catchments are those with the highest 10% of nitrate levels in the MfE Environmental Reporting River Water Quality dataset found here. Catchments where the predominant sources of nitrate are non-pastoral in origin are excluded.
Under Option 1, a per-hectare cap, or threshold, for nitrogen losses will be set for each sub-catchment with similar soil type and rainfall. This threshold will be based on a ranking of nitrogen losses from farms within each sub-catchment, and could be set at the 90th percentile, or the 70th, or a point between. Feedback is sought on where this threshold should be set.
This is only one of the options being consulted on, The areas indicated are provisional and may not equate to areas included in regulation.

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

This dataset was first added to MfE Data Service on 13 Aug 2019.
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.

This dataset was first added to MfE Data Service on 14 Aug 2019.
This dataset includes three “packages” of information, each with multiple variables. The packages include:
For further detail on the modelling methods and discussing results, see Hicks, M., Semademi-Davies, A., Haddadchi, A., Shankar, U., Plew, D. (2019) Updated sediment load estimator for New Zealand. NIWA Client Report No. 2018341CH, prepared for Ministry for the Environment. January 2019. Available online: www.mfe.govt.nz/publications/fresh-water/updated-s...
Note that some portions of this dataset refine and update 2011 modelling on suspended sediment loads across New Zealand, whereas other components, especially the coastal package, report new modelling results.

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.
