Lincoln County Lake Quality
West Virginia, 1 lake — no lake here has enough monitoring data for a grade
Lincoln County has 1 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.
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. Upper Mud River Reservoir (—) is the cleanest in the county.
