The Little Para River is a freshwater stream that flows west
from the Mount Lofty Ranges near Upper Hermitage into the Barker
Inlet. The Little Para is a water supply catchment, with the Little
Para Reservoir near its middle. Land uses in the catchment are
a mixture of broad-acre grazing, some perennial horticulture,
forestry and the fringing residential area of the north-eastern
suburbs of Adelaide. Elevated turbidity and nutrient levels are
the most likely water quality problems.
The monitoring site is located at the flow gauging station just
downstream of the Little Para Reservoir. Stream
flow data for the site is available from the Department
of Water, Land and Biodiversity Conservation. Extensive reed
beds grow in the channel and the riparian vegetation is predominantly
native with tall eucalypts and a grassy undergrowth. >>

The indicators that are measured in the Little Para River are
nutrients (nitrogen and phosphorus), turbidity and salinity.
The concentrations of these indicators are used to classify the
water chemistry as being in good,
moderate or poor
condition, according to the needs of aquatic ecosystem protection.

The water quality results for this monitoring period were generally
consistent with previous results, with elevated nitrogen concentrations
(mainly due to oxidised nitrogen).
The oxidised nitrogen concentration in the Little Para River
does not appear to follow a clear seasonal trend, although it
is likely to be influenced by local groundwater inflows that may
contain elevated nitrate concentrations.
The Adelaide
and Mt Lofty Ranges Natural Resources Management Board is
also developing a regional NRM Plan, which will address catchment
management issues affecting the condition of watercourses such
as the Little Para River.
