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 1990), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
10 ft Secchi depthClear
Last measured Jun 12, 2023. 30 readings on record, 2015 to 2023.
Typical summer clarity (June to September): 10 ft, clear, from 19 readings (2015 to 2023).
Measured at the monitoring station named “Twin Lake North - 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).
