Swift County Lake Quality
Minnesota, 3 lakes, average grade D (Poor)
Only 3 lakes in Swift 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. On average, Swift County lakes grade D, with phosphorus loading and reduced clarity showing up across most of the dataset.
The county's lakes lean shallow, which makes the grades sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest lake on the books is Camp Lake (D); the most-stressed is Unnamed Lake (F).
