| Measure | Reading | Where it sits |
|---|---|---|
| Water clarity (Secchi depth) | 21.7ft | 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. | |

From the 2023-08-01 survey
A temperature-dissolved oxygen profile was collected in the deepest basin on Chase Lake on August 1, 2023, to evaluate the amount of cold, oxygenated water (i.e., oxythermal habitat) available to Cisco, also known as Tullibee. Based on the profile, the top of the thermocline (i.e., the location in the water column…
