Ecological health
We collect two samples of macroinvertebrates, one from riffle
(or flowing water) habitat and one from edge (still water) habitat.
The diversity of the macroinvertebrate community is used to describe
ecological health as being in good,
moderate or poor
condition.

Since monitoring began in 1994, the edge habitat has been consistently
rated in good condition. A riffle habitat is usually available
as water flows over willow roots, however a riffle was not present
on this occasion. Usually the riffle is also rated in good condition.

Water chemistry
The indicators that are measured in Scott Creek 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.

These classifications are consistent with previous results. The
Scott Creek catchment is in relatively good condition, which is
largely why the nutrients and turbidity are usually good.
