| Measure | Reading | Where it sits |
|---|---|---|
| Water clarity (Secchi depth) | 5.3ft | Measured, not scored How deep a black-and-white disk stays visible from the surface. Higher is clearer. |
| Total phosphorus | 37µg/L | Measured, not scored The nutrient that most limits algae growth in freshwater. More phosphorus, more algae potential. |
| Chlorophyll-a (algae) | 3.9µg/L | Measured, not scored The green pigment in algae — a direct measure of how much algae is in the water. |
