Devils Lake

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 1981), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Water clarity

14.8 ft Secchi depthClear

Last measured Aug 12, 2026. 28 readings on record, 2007 to 2026.

Typical summer clarity (June to September): 16.4 ft, clear, from 14 readings (2013 to 2026).

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.

Recorded in open fish survey and museum records (GBIF). A record shows a fish was found near this lake in that year, not that it is there now, and says nothing about how many. Most coordinates are rounded to about 1 km, so a record is attached only when one lake is the clear match.

Open fish survey and museum records from GBIF; datasets are listed on the sources page. Checked Oct 23, 2026.
