Union County Lake Quality

Arkansas, 16 lakes, measured by Arkansas DEQ

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. The 16 monitored lakes in Union 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.
