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

McCormick Lake Access1

Numbered dots are boat landings; tap one for directions. The list below has the same numbers. 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

2 ft Secchi depthLowOlder reading

Last measured Aug 26, 2016. 1 reading on record, 2016.

Only one reading is on record.

Nothing has been measured in the last 5 years, so this may not match the lake today.

Secchi depth is how far down a white disk stays visible. A bigger number means clearer water. Clear means a Secchi depth of 10 feet or more, moderate 5 to 10 feet, low under 5 feet.

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).

Fish recorded near this lake

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.

Boat landings

Wisconsin DNR public boat access sites. Checked Oct 23, 2026.
