State of Water Quantity
The 2012 Hydrometric and Climatological State of Environment Report (the Report) is the fourth regional summary of hydrometric and climatological information produced by the West Coast Regional Council (the Council). The Report covers a range of hydrometric and climatological statistics looking at both long term data, and also data from 2005-2011. The data analysed and reported on in this Report is sourced from rainfall, river flow and climate sites throughout the West Coast Region. These sites are operated by a range of agencies including the Council, NIWA, Metservice, Meridian and Trustpower.
The analysis is broken down into three sections: climate, rainfall and river flow summarising trends/results both long-term and for the 2005 – 2011 period for all sites (climatological or hydrometric).
