Rainbow Springs Lake

Outline

Drawn from the DNR's 24K hydrography (surveyed 1994), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Water clarity (satellite estimate)

• Summer 20167.5 ft (38 satellite pixels)
• Summer 201710.7 ft (38 satellite pixels)

No one has measured this lake's clarity in the monitoring data. These are estimates from satellite images of two summers only, so they may not match the lake today.

Secchi depth is how far down a white disk stays visible. A bigger number means clearer water. The estimate tops out at 16 feet.

Landsat satellite estimates published by the Wisconsin DNR (summers 2016 and 2017), averaged over the lake's outline. Informational use only.
