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 1973), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
3 ft Secchi depthLowOlder reading
Last measured Sep 3, 2002. 130 readings on record, 1986 to 2002.
Nothing has been measured in the last 5 years, so this may not match the lake today.
Measured at the monitoring station named “STRUM LAKE - DEEP HOLE”.
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).
