Goshen County Lake Quality
Wyoming, 3 lakes, average grade F (Very Poor)
Only 3 lakes in Goshen County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county. The county average is F — the most-stressed bracket in our rubric. Most monitored lakes here show persistent nutrient loading and algal pressure.
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. Hawk Springs Reservoir (D) is the cleanest in the county.
