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 South Twin Lake only with neighbouring lakes in Wisconsinthat carry a letter of their own. A nearby lake with too little recent sampling has no letter to compare, so it is absent from the table rather than ranked below. Where a driving distance is not published for a lake, the table says so instead of estimating one.
