Pomme de Terre Lake vs Ten Mile Lake
Water quality, depth, fish species, and recreation comparison.
Ten Mile Lake has a higher water quality grade (B, Good) than Pomme de Terre Lake (D, Poor). Both are in Minnesota.
Both Pomme de Terre Lake and Ten Mile 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. The grades are meaningfully apart: Ten Mile Lake grades a B while Pomme de Terre Lake grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Ten Mile Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
