Latest individual samples: Secchi 15 ft (2022-09-06), chlorophyll-a 2 µg/L (2021-08-15), and total phosphorus 14 µg/L (2020-06-21).
Secchi clarity is how deep a black-and-white disk stays visible from the surface — more feet means clearer water.
Chlorophyll-a is an algae pigment; higher values signal more algae in the water column.
Total phosphorus is a nutrient that feeds algae and aquatic plants. It is not a weed survey — depth, bottom type, water movement, and management change the actual lake experience.
