Lake Ōhau lake levels

The measurements are shown in metres above sea level. The minimum consented level of Lake Ōhau is 519.45m. Levels above 520.4m result in water discharging over the outlet weir and into the Upper Ōhau River. Levels above 520.25m are subject to minimum outflow requirements via the Ōhau Canal.

These levels shown are provisional and are 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.

Meridian voluntarily reports hydro spill as part of the Voluntary Hydro Spill reporting regime.
