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 1990), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.
Water clarity
13 ft Secchi depthClearOlder reading
Last measured Apr 21, 1998. 1 reading on record, 1998.
Only one reading is on record.
Nothing has been measured in the last 5 years, so this may not match the lake today.
Measured at the monitoring station named “East Twin Lake at Deepest Spot”.
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.
