Stone County Lake Quality

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 recent nutrient and algae readings, so the county-level summary covers the full set rather than a monitored subset. Taken together, the monitored lakes of Stone County sit near the low-nutrient end of the Missouri range.

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 has the lowest nutrient and algae readings in the county.
