Outline

Silver Birch Park Boat Landing1

Numbered dots are boat landings; tap one for directions. The list below has the same numbers. Drawn from the DNR's 24K hydrography (surveyed 1992), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Water clarity

1 ft Secchi depthLowOlder reading

Last measured Jul 20, 2016. 19 readings on record, 1993 to 2016.

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.
