Stone County Lake Quality
Missouri, 1 lake, average grade A (Excellent)
Stone County has 1 monitored lake — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. Every one of those lake carries an A–F grade, so the county-level summary covers the full set rather than a monitored subset. On average, Stone County lakes grade an A. That puts it near the top of the Missouri county ranking.
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. Table Rock L. @ Mouth of James R. Arm Lake (A) is the cleanest in the county.
