Monroe County Lake Quality
Arkansas, 16 lakes, measured by Arkansas DEQ
There are 16 monitored lakes in Monroe County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. The 16 monitored lakes in Monroe County carry whatever clarity, phosphorus, and chlorophyll-a readings Arkansas DEQ 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.
