Greater Wellington Regional Council (GWRC) operates a hydrometric network for measuring rainfall, river levels and flow, lake and wetland levels, groundwater levels and soil moisture. This report contains key results from the Hydrology State of Environment (SoE) monitoring programme. Summaries of the recorded data are compared to long term averages, and any significant hydrological events are detailed.
