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]

Culture and history

Lake Ōmāpere is of great cultural and environmental value to Māori tangata whenua.[4]

In May 1845 a battle occurred during the Flagstaff War at the pā of Hone Heke at Puketutu (Te Mawhe Pā) 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]

Water quality and ecology

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]
