Posey County Lake Quality
Indiana, 3 lakes, measured by IDEM
Posey County has 3 monitored lakes — 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. The 3 monitored lakes in Posey County carry whatever clarity, phosphorus, and chlorophyll-a readings IDEM has published, shown as reported.
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.
