Kaituna Catchment Control Scheme
The Kaituna Catchment Control Scheme includes the catchments of Lakes Rotorua and Rotoiti as well as the catchment of Kaituna River. The whole catchment area covers 1,250 square kilometres (125,000 ha).
The Kaituna River starts at the outlet of Lake Rotoiti at Okere Arm and enters the sea at Te Tumu near Maketu. It passes through a steep, narrow gorge, well known for its white water rafting, before meandering through the alluvial terraces of the mid Kaituna River and the peat and sand deposits of the lower Kaituna basin.
Lakes Rotorua and Rotoiti contribute a large proportion of the everyday flows. The Mangorewa River is a majority tributary, which contributes greatly to flood flows in the Kaituna River. Other significant tributaries include the Waiari, Ohineangaanga, Raparapahoe and Kopuaroa Streams, which drain the hill country behind Te Puke.
Scheme meeting notes
Bay of Plenty Regional Council has a network of liaison people for each of the EBOP-managed river and drainage schemes in the region. The liaison group members are the representatives for the ratepayers of their particular scheme. Meetings are held with the liaison groups in March and November of each year. Extraordinary meetings are called as required. Below is a copy of the notes from the last cycle of liaison group meetings. For previous later meeting notes contact us on the details below.
In the Upper Kaituna area the scheme consists of:
- Significant areas of soil conservation works where most streams have been fenced and planted with native or exotic vegetation or allowed to regenerate.
- Flood protection stopbanks on Waingaehe, Puarenga, Utuhina and Waiowhero Streams through the Rotorua urban area.
- Stream clearing, straightening and construction of floodways on Ngongotaha and Waiteti Streams to minimise flooding.
- Level control structures on Lakes Rotorua (Ohau Channel stop logs) and Rotoiti (Okere control gates). For more information on the Okere Gates and Ohau Weir, please click here.
In the Lower Kaituna area the scheme consists of:
- 67 kilometres of stopbank.
- 88 kilometres of canals and drains.
- Seven pump stations (and 14 pumps).
- Three weir structures.
- Five major floodgate structures.
- Riverbank protection - six kilometres of planting and 1.5 kilometres of rock or rubble.
- Mole/groyne structure at the river mouth.
