River flow data
We record water levels at 145 river and lake sites in Canterbury, from the Clarence River/Waiau Toa in the north to the Waitaki River in the south. We measure river flow at 131 of these sites and this information is combined with water level data to produce continuous flow records. We report this alongside data from 18 other sites recorded by partner agencies such as the National Institute of Water and Atmospheric Research and Christchurch City Council.
