Meeker County Lake Quality

Minnesota, 23 lakes, average grade D (Poor)

Meeker County's 23 graded lakes fall in the moderate-density bracket for Minnesota. The county-level average smooths over real differences — a single agricultural watershed near the southwest corner can pull the average down even if the rest of the county runs clean. The county-wide average grade is D — water quality issues are persistent across most of the monitored basins. 6 lakes fall into the F bracket outright.

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 Minnie-Belle Lake (A); the most-stressed is Unnamed Lake (F).
