Water Turbidity
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 6 benchmarks together — the OptimalRange form drives the primary score, while 5 guard(s) constrain the result.

Evidence & Context
An aspirational target for systems demonstrating 2 very good ecological condition is a median turbidity of ≤ 5 NTU.
Water turbidity measured in Nephelometric Turbidity Units (NTU) representing the clarity of water in streams and water bodies.
This aspirational benchmark represents a very good ecological condition target for water turbidity in streams and water bodies within Australian Temperate Dry Woodlands and Native Grasslands under agricultural crop production.
This target aligns with the 'Very Good' ecological condition category cited by CSIRO and represents an excellent state of water clarity achievable in managed agricultural landscapes.
