Baldwin County Lake Quality

Alabama, 26 lakes, average grade A (Excellent)

There are 26 monitored lakes in Baldwin County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. 1 of those lake carry an A–F grade. The county-level summary describes that subset, not every water body listed. The county's average grade is A — among the cleanest in Alabama. 1 lakes pull an A on their own, and almost none fall into the D or F brackets.

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 Shlb Lake (A); the most-stressed is Shlb Lake (A).

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.
