The DNR lists this lake's watershed (Lake Michigan) as suspect or infected with VHS, a fish virus. The listing covers the watershed, not a test of this lake. About VHS

Size

347 acres

Max depth

27 ft

DNR lake type

Simple, Cool, dark water color

A cool-water lake type: the DNR groups it with lakes that stay cooler through summer. This describes the lake type in general, not this lake in particular.

Outline

Drawn from the DNR's 24K hydrography (surveyed 1982), 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 20163.3 ft (1,341 satellite pixels)
  • Summer 20174.1 ft (1,446 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 15 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).
