Sanpete County Lake Quality
Utah, 13 lakes, measured by Utah DWQ
Sanpete County has 13 monitored 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. 5 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. Most monitored lakes in Sanpete County carry favourable nutrient and algae readings for Utah.
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. Ferron Reservoir has the lowest nutrient and algae readings in the county.
