as a mixture of steep slopes in the south and south-east
forming the upper reaches, which fall through to rolling
country and then gently sloping towards Otara Creek and
Otara Lake. |

| Land Use |
Land in the upper parts of the Otara Creek catchment
between Chapel Road and the eastern boundary hills is
still currently rural and largely in livestock farming
including dairying, beef cattle, horses and sheep. Most
of that part of the catchment is earmarked for the future
East Tamaki/Flatbush Integrated Development Area. The
area incorporates aspects of intensive residential development
in close proximity to shopping, service and greenfield
areas. |

| Water
Quality |
Water quality in the upper Otara Creek tributaries currently
reflects its rural nature and is relatively good compared
to the lower Otara Lake areas of the creek. The intensive
industrial and commercial East Tamaki corridor in the
lower part of the catchment is drained by two un-named
Otara Creek tributaries. They feed directly into the Otara
Lake. |

| Flood
Hazard |
For the Otara Creek Sub-Catchments that do not have
a current CCDC, Council officers do not have any areas
within them that are identified as a major flood concern.
Most of the recorded flooding problems are within the
catchments which already have a CCDC; Catchments 644 &
645. |
