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 Mary Lake only with neighbouring lakes in Minnesotathat 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.
