Long 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 1971), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Water clarity

7.5 ft Secchi depthModerate

Last measured Sep 1, 2026. 209 readings on record, 1991 to 2026.

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.
