Lake Ōmāpere is the largest lake in the Northland Region of New Zealand. It is located to the North of Kaikohe.
The lake sits within the Kaikohe-Bay of Islands volcanic field. The lake was formed when an ancient lava flow blocked a valley, forming the northern shoreline. [1] [2] It is five kilometres in length and covers 12.3 km2, however it is only 2.6 metres deep (and as low as 1.5 m during summer). The lake has few inflow streams, mostly in the southern part of the lake. The Utakura River (south-western margin) is the main outflow which goes to the Hokianga Harbour. The lake catchment is predominantly pasture, with a few areas of native scrub and mature bush. [3]
Lake Ōmāpere is of great cultural and environmental value to Māori tangata whenua. [4]
In May 1845 the Battle of Puketutu, an engagement of the Flagstaff War, occurred at the pā of Hōne Heke at Puketutu, on the shores of Lake Ōmāpere. [5]
The lake level was lowered between 1903 and 1929, [6] but by 1947 silting had restored much of its level. [7]
The water quality in the lake is generally poor and the lake is prone to blooms of toxic algae. [8] The lake is monitored by Northland Regional Council, and the environmental information can be viewed on the LAWA website. [9]
The Lake Ōmāpere Restoration and Management Project aims to develop and implement a voluntary lake management strategy that will work towards improving the health of the lake and help assist the Lake Omapere Trustees in their role as kaitiaki. [10]
