Taieri FMU
The Taiari/Taieri Freshwater Management Unit (FMU) covers the entire Taieri River catchment, reaching from Taieri Mouth across the Taieri Plain into the Strath Taieri and Maniototo Basins.
The Taieri River is the fourth-longest in New Zealand. Water quality is generally good, but some lower Taieri Plain tributaries are degraded. Water quality is affected by pressures such as intensive agricultural land use, urban land uses and stream modification.
Notable freshwater bodies in the catchment are the Taieri River and its tributaries (e.g., the Kye Burn, Sow Burn, Deep Stream), Lakes Mahinerangi, Waipori, and Waihola, and the Scroll Plain wetlands.
The Taieri is an important water source for irrigation, and flows are significantly reduced during the irrigation season. The FMU has two hydroelectricity plants – one in the Upper Taieri and the other in the Waipori catchment. Most of Dunedin city’s water supply comes from the Taieri River downstream of Sutton.
The catchment area encompasses all or parts of several mountain ranges – the Rock and Pillar Range (1450m), Lammermoor (1160m) and Lammerlaw (1210m) Ranges, the eastern slopes of Rough Ridge (950m), the southern slopes of the Kakanui Mountains (1600m), the lower crests of Taieri Ridge (660m) and Maukaatua (Maungatua) (895m).
