Lake Okareka is a shallow lake that stratifies for approximately six months of each year. It has the second highest density of human habitation, increasing during summer months.
Lake Okareka is linked to Lake Tarawera via the Waitangi Spring.
There are few problems with the lake, however during periods of deoxygenation of the bottom waters nutrients are released from the sediments. The quality of the lake is poorer than the baseline quality requirements of EBOP's regional plan (EBOP, 2000).
The Lake is threatened by the impacts of existing and future urban and rural development as well as natural hazards. Urban septic tanks and the fluctuating lake levels are also issues of concern.
