Pepin County Lake Quality
Minnesota, 1 lake — no lake here has enough monitoring data for a grade
Only 1 lakes in Pepin County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county.
Many of the county's lakes are deep glacial basins — over 50 feet at their deepest point — which gives them thermal stratification and a buffer against summer warming. Pepin Lake (grade —) is the cleanest in the county.
