Brevard County Lake Quality

Florida, 23 lakes, average grade C (Fair)

Brevard County's 23 graded lakes fall in the moderate-density bracket for Florida. 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. Brevard County averages to a C. The distribution behind that average matters more than the letter: a few stressed lakes versus many decent ones can produce the same average as the inverse.

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 Brevard-Clear Lake (B); the most-stressed is Lwc Lake (D).

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.
