Izard County Lake Quality
Arkansas, 2 lakes, average grade A (Excellent)
Izard County has 2 graded 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. On average, Izard County lakes grade an A. That puts it near the top of the {{stateName}} 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. Crown Lake (A) is the cleanest in the county.
