River heights and rainfall

Horizons provide useful information on ground water, soil moisture, turbidity and water temperature. During heavy rain or a flood event, you can use this up-to-the-minute information from throughout our Region to make decisions.

We have developed models that will predict river level from rainfall within the catchments. These forecasts use data based on upstream flow, upstream rainfall and rainfall forecasts. The most accurate forecasts are based on upstream flow and they become increasingly less accurate the more they rely on upstream rainfall and then forecast rainfall. Flood forecasting for the Manawatu River and its major tributaries downstream of the Manawatu Gorge, as well as the Whanganui River, are currently available on our website.

Forecasts for the Manawatu river and its major tributaries as well as for the Whanganui, Whangaehu, Turakina and Rangitikei rivers are now available.
