| Measure | Reading | Where it sits |
|---|---|---|
| Water clarity (Secchi depth) | 1.55m | Measured, not scored How deep a black-and-white disk stays visible from the surface. Higher is clearer. |
| Total phosphorus | 15.5µg/L | Measured, not scored The nutrient that most limits algae growth in freshwater. More phosphorus, more algae potential. |
| Chlorophyll-a (algae) | 10.5µg/L | Measured, not scored The green pigment in algae — a direct measure of how much algae is in the water. |
