Lake Okaro
The meaning and origin of the name has been lost over time, but Lake Ōkaro is considered to be of significant taonga to Ngāti Whaoa / Ngāti Tahu.
Lake Ōkaro/Ngakaro is the smallest of the Rotorua lakes under public management. Appreciated for its quiet rural setting, it is surrounded by farms and is also a popular water-skiing spot. The lake has had a significant algae problem due to the levels of nitrogen and phosphorus nutrients which have increased over several decades. The nutrient-rich deposits over the catchment from the 1886 Tarawera eruption, have an ongoing effect on the lake's water quality.
