Flood protection and drainage works scaled back due to COVID19 alert level 4
Now that we are in Alert level 4, Environment Canterbury has scaled back all non-essential flood protection and drainage work in our riverbeds. We will be completing works that protect life, homes and critical infrastructure only. All of our flood prediction tools, rain gauges, and river flow gauges will continue to operate as an Essential Service. If you have any questions about works in your area please contact floodbylaw@ecan.govt.nz

We record rainfall at 82 sites throughout Canterbury, measuring intensities in 7.5 or 15-minute intervals depending on the site’s proximity to the Southern Alps/Kā Tiritiri o te Moana, and report it alongside data measured by partner agencies at 11 other sites. Data can be used to assess storm intensities, provide the basis for flood warnings and provide daily, monthly or annual rainfall totals.
