River Heights & Rainfall

Horizons provides 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 important decisions.

We've developed models that predict river levels based on rainfall within 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 forecast rainfall. 

Forecasts for the Manawatū River and its major tributaries, as well as for the Whanganui, Whangaehu, Turakina and Rangitīkei Rivers, are now available.
