Beckman 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 2008), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Water clarity

2 ft Secchi depthLowOlder reading

Last measured Aug 7, 2019. 10 readings on record, 2016 to 2019.

Typical summer clarity (June to September): 5 ft, moderate, from 10 readings (2016 to 2019).

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.

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.
