Antrim County Lake Quality

Michigan, 28 lakes — no lake here has enough monitoring data for a grade

Antrim County's 28 monitored lakes fall in the moderate-density bracket for Michigan. 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. No lake in Antrim County has enough sampling behind it for an A–F grade yet. The 28 monitored lakes below carry whatever clarity, phosphorus, and chlorophyll-a measurements exist.

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.

NR = not rated: there is not enough recent sampling to support a letter. That is EPA Integrated Reporting Category 3 (insufficient information), not a failing grade. How grading works.
