Current lake levels for the Waikato Taupo system are displayed below:

Lake Levels

The diagram above shows the storage capacity of each lake as a percentage of the total storage for the Taupo Waikato system. (E.g. Lake Taupo has 93% of total storage, while the lake with the smallest storage Aratiatia has just 0.1% of total storage). The diagram does not depict current water storage or lake levels. This information is available by selecting the lake you wish to view from the drop down box above at the top of the page.

The percentages have been calculated assuming all lakes were full and using Lake Taupo's required maximum level of 357.25m above sea level.

Mighty River Power is pleased to bring you up to date information on Lake Taupo and Waikato hydro lake levels in the form of graphs for each lake.

The measurements for the levels shown are based on height in metres above sea level. For example the levels shown for Lake Taupo will, other than in exceptional circumstances, be between 355.85m and 357.39m above sea level. Differing levels within the minimum and maximum levels are shown for each of the hydro lakes - Aratiatia, Ohakuri, Atiamuri, Whakamaru, Maraetai, Waipapa, Arapuni & Karapiro.

Actual levels on each lake may vary from those shown here. This is because, within the operating water level range that is established for each of the lakes including Lake Taupo, the company supplies water to each of its power stations to meet national demand for electricity. Daily changes in electricity demand, and shifts in catchment inflows as a result of weather influences, can result in the actual levels at any time being different from those shown here. These levels shown are provisional and intended to be indicative only and for general information purposes, and do not try to show what actual levels will be at any particular time or place. If you intend to use the hydro lakes for any recreational or other purpose, please ensure that your activity can be safely carried out if the actual water levels change.
