Outline

Sand Lake Park Access1

Numbered dots are boat landings; tap one for directions. The list below has the same numbers. Drawn from the DNR's 24K hydrography (surveyed 1980), so the shape is approximate and a landing can sit a little off the shore. Open the DNR lake map.

Fish recorded near this lake

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.

Boat landings

Wisconsin DNR public boat access sites. Checked Oct 23, 2026.
