DNR lake type
Simple, Warm, dark water color
A warm-water lake type: the DNR groups it with lakes that warm up through summer. This describes the lake type in general, not this lake in particular.
Outline
Numbered dots are boat landings; tap one for directions. The list below has the same numbers. Drawn from the DNR's 24K hydrography (surveyed 1980), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity (satellite estimate)
- Summer 20162 ft (1,420 satellite pixels)
- Summer 20173.8 ft (1,213 satellite pixels)
No one has measured this lake's clarity in the monitoring data. These are estimates from satellite images of two summers only, so they may not match the lake today.
Secchi depth is how far down a white disk stays visible. A bigger number means clearer water. The estimate tops out at 16 feet.
Landsat satellite estimates published by the Wisconsin DNR (summers 2016 and 2017), averaged over the lake's outline. Informational use only.

A computer model of this lake's typical weather and water, built from 11 years, 2005 to 2019. Ranges show the middle half of years. The model was not calibrated against measured temperatures for this lake. It is an estimate, not a measurement.
Modeled: U.S. Geological Survey lake temperature data release (doi:10.5066/P9CA6XP8).

Recorded in open fish survey and museum records (GBIF). A record shows a fish was found near this lake in that year, not that it is there now, and says nothing about how many. Most coordinates are rounded to about 1 km, so a record is attached only when one lake is the clear match.
Open fish survey and museum records from GBIF; datasets are listed on the sources page. Checked Oct 23, 2026.
