Cloud County Lake Quality

Cloud County holds 1 monitored lake. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. Every one of those lake carries recent nutrient and algae readings, so the county-level summary covers the full set rather than a monitored subset. The monitored lakes here are mostly shallow, productive basins where summer algae is common; each lake page shows its own readings beside the EPA condition class.

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. Jamestown Wildlife Area Lake has the lowest nutrient and algae readings in the county.
