Wabasha County Lake Quality
Minnesota, 2 lakes — no lake here has enough monitoring data for a grade
Only 2 lakes in Wabasha 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.
Most of the county's monitored lakes are shallow — under 50 feet — which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed. Robinson Lake (—) is the cleanest in the county.

NR = not rated: the monitoring record does not meet the evidence bar for a grade. That is EPA Integrated Reporting Category 3 (insufficient information), not a failing grade. How grading works.
