| Measure | Reading | Where it sits |
|---|---|---|
| Water clarity (Secchi depth) | 8.9ft | Measured, not scored How deep a black-and-white disk stays visible from the surface. Higher is clearer. |
| Total phosphorus | No reading The nutrient that most limits algae growth in freshwater. More phosphorus, more algae potential. | |
| Chlorophyll-a (algae) | No reading The green pigment in algae — a direct measure of how much algae is in the water. | |
| Trophic state (TSI)Carlson's 0–100 index of how much algae a lake can support, from clarity, phosphorus and chlorophyll-a. | 46 | Mesotrophic OligotrophicMesotrophicEutrophicHypereutrophic |

A temperature-dissolved oxygen profile was collected in the deepest basin on Davis Lake on August 24th, 2023 to evaluate the amount of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Trout. Based on the profile, the top of the thermocline (i.e., the location in the water column with the sharpest…
