Lincoln County Lake Quality

Wyoming, 15 lakes, average grade B (Good)

Lincoln County's 15 graded lakes fall in the moderate-density bracket for {{stateName}}. 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. With an average grade of B, Lincoln County sits comfortably above the {{stateName}} median.

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. Fontenelle Reservoir (A) is the cleanest in the county.
