Garden County Lake Quality

Nebraska, 80 lakes, average grade B (Good)

Garden County in Nebraska carries 80 monitored lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. 1 of those lake carry an A–F grade. The county-level summary describes that subset, not every water body listed. With an average grade of B, Garden County sits comfortably above the Nebraska 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. Crescent Lake (B) is the cleanest in the county.

NR = not rated: there is not enough recent sampling to support a letter. That is EPA Integrated Reporting Category 3 (insufficient information), not a failing grade. How grading works.
