MeasureReadingWhere it sits
Water clarity (Secchi depth)4.5mMeasured, not scored

How deep a black-and-white disk stays visible from the surface. Higher is clearer.

Total phosphorus10µg/LMeasured, not scored

The nutrient that most limits algae growth in freshwater. More phosphorus, more algae potential.

Chlorophyll-a (algae)1.5µg/LMeasured, not scored

The green pigment in algae — a direct measure of how much algae is in the water.
