Long Lake vs Pelican Lake
Water quality, depth, fish species, and recreation comparison.
Pelican Lake has a higher water quality grade (A, Excellent) than Long Lake (A, Excellent). Both are in Otter Tail County, Minnesota.
Both Long Lake and Pelican Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. These two are within a letter of each other on the rubric — Long Lake (A) versus Pelican Lake (A). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
Long Lake
Good clarity, visible to about 11.8 ft.
