Latest individual samples: Secchi 3 ft (2024-04-29), chlorophyll-a 71 µg/L (2012-09-06), and total phosphorus 109 µg/L (2012-09-06).
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.

Depth FAQ
How deep is Forestville Flowage?
Forestville Flowage is 5 feet deep at its deepest point and averages about 2 feet, according to Wisconsin DNR records.
Is there a free depth map of Forestville Flowage?
