Rainfall & Flow
Mt Ruapehu
Our core business of hydro generation is based on the natural flows and catchments of the Waikato River - and ultimately, the weather. The limited storage available in both Lake Taupo and the hydro lakes on the river mean that we are very reliant on regular rainfall to provide inflows to the system.
Modern forecasting techniques enable Mighty River Power to operate the Waikato hydro system efficiently by responding to weather patterns and instant changes in electricity demand.
To do this we work closely with other agencies, sharing and analysing the most up-to-date weather data and information about river flows in the Waikato and the major tributaries feeding the catchment.
You can access information about river levels and rainfall in the region through Environment Waikato's website or call our Flowphone on 0800 820 082.
