Warren County Lake Quality

Missouri, 16 lakes, average grade C (Fair)

Warren County's 16 graded lakes fall in the moderate-density bracket for Missouri. 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. Warren 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.

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. Alpine Lake (A) is the cleanest in the county.
