Water quality quick take
From Wisconsin DNR / Citizen Lake Monitoring readings at Little Sand Lake - Deep Hole T35r13e31.
Last sampled Sep 2022
Through 2022, somewhat hazy water — summer clarity of 8.5 ft is lower than most monitored Wisconsin lakes.
Based on July–August 2021 averages across 5 volunteer readings.Water claritySecchi disk depth

Summer averages (July/August)
July/August means; counts in parentheses show how many samples went into each average.
| Year | Secchi | Chlorophyll-a | Total phosphorus |
|---|---|---|---|
| 2022 | — | 12.0 µg/L (1) | — |
| 2021 | 8.5 ft (3) | 6.0 µg/L (2) | — |
Latest individual samples: Secchi 8 ft (2021-08-04) and chlorophyll-a 5 µg/L (2022-09-21).
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.
