What the comparison covers
A grade on LakeQuality comes from EPA Water Quality Portal samples: phosphorus, nitrogen, chlorophyll-a and turbidity, measured against EPA National Lakes Assessment ecoregion classes. Secchi clarity is shown and is not scored. This page compares Newell Pit Lake only with neighbouring lakes in Iowathat carry a letter of their own, within 30 miles.

Where a driving distance is not published for a lake, the table says so instead of estimating one.
