This dataset was first added to MfE Data Service on 18 Aug 2021.
These data are the raw river water quality observations used to calculate state and trends for the period ending 2017.
It contains ten parameters of water quality based on measurements made at monitored river sites:

This dataset was last updated on MfE Data Service on 22 Apr 2021.
23 April 2021: A new version of this data set has been published. It includes data on 4 parameters (Ammoniacal nitrogen (adjusted), Escherichia coli, Macroinvertebrate Community Index and Total Phosphorus) that had been missing from the file that was published as part of the Our freshwater 2020 release in April 16 2020. The updated data set also includes data on DRP for all 593,337 REC segments, since the file from April 16 2020 only had data for 255,860 of these segments.
16 April 2020: Subsequent to publication in April 2019 we discovered two small errors with this dataset. These included:
In addition, flow data from TopNet has also been updated.
These changes have a minor impact on overall results. These changes have have been corrected, and are republished here, as part of the Our freshwater 2020 release.
IMPORTANT INFORMATION
1) The main (cleaned) dataset is structured by each row having a nzsegment and np_id combination. A large dataset (~ 1 GB) has resulted, due to the inclusion of the ANZG/NOF columns and the 10 different np_id values. There are ~ 6 million rows to this dataset, however a 32-bit version of Microsoft Excel will only display/download ~ 1 million rows. __A DBMS, statistical or GIS application is needed to view the entire dataset__.
2) A smaller raw dataset (see attachments) is provided which structures each row relating to a river segment and drops the ANZG/NOF columns.
3) The attached metadata/date quality report provides further information on the NOF, ANZG and the "McDowell meet/doesnt meet" attachment.
This dataset contains ten parameters of water quality based on measurements made at monitored river sites:
