Measure	Reading	Where it sits
Water clarity (Secchi depth)	1.1m	Measured, not scored How deep a black-and-white disk stays visible from the surface. Higher is clearer.
Total phosphorus	15.9µg/L	Measured, not scored The nutrient that most limits algae growth in freshwater. More phosphorus, more algae potential.
Chlorophyll-a (algae)	5.6µg/L	Measured, not scored The green pigment in algae — a direct measure of how much algae is in the water.
