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.
Evidence & Context
Proposed Benchmark (Wet Season Baseflow / Recessional Flow): < 10 NTU.
Water turbidity is a fundamental optical property of water, quantifying its clarity or, conversely, its cloudiness.
Proposed benchmark for high environmental health during wet season baseflow or recessional flow in Tropical Monsoonal Savannas.
The horticultural area of the Upper Laura River showed a median wet season baseflow of 6.59 NTU (80th percentile 8.13 NTU). Some less disturbed Cape York streams, like the Archer River, also showed values in this range (3.7 - 8.9 NTU).
