LakeQuality

Of the 3 lakes neighbouring it with nutrient and algae readings on record, none reads lower than Altoona Lake, so Altoona Lake is the cleanest measured water among its neighbours. Lakes nearby without enough recent sampling to earn a letter are not part of that comparison.

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 Altoona Lake only with neighbouring lakes in Wisconsinthat carry readings 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.
