Cleaner Lakes Than Maggotte L. Lake

Reading the cohort

Within 30 miles of Maggotte L. Lake, 4 water bodies score higher than its Grade B on the same EPA water-quality metrics. That density of cleaner options is itself a signal — when several nearby lakes score better on the same indicators, the issues at Maggotte L. Lake are typically lake-specific (depth, watershed inflow, stratification pattern) rather than regional. The choice for a swim, paddle, or fishing trip is genuinely between meaningfully different water bodies, not between marginal differences in the same dataset.

The nearest cleaner alternative — Waweig L. Lake in Thunder Bay District County — sits 16.3 miles from Maggotte L. Lake, putting it firmly in "destination trip" rather than "neighborhood swap" range. The water-quality gap has to be the deciding factor; for a casual outing, Maggotte L. Lake is the practical choice and the cleaner options are reserved for purpose-specific visits.

The EPA water-quality grading combines clarity (Secchi depth), phosphorus, and chlorophyll-a measurements from state environmental sampling. A higher letter grade reflects measurably cleaner water on those indicators, not subjective beauty or access quality — a Grade A lake might have worse boat-launch facilities or shoreline access than a Grade C neighbor, so the ranking is one input alongside the rest of trip planning. See the methodology page for the full grading formula.

How this list is built

Every lake on LakeQuality has a calculated grade from EPA Water Quality Portal samples — secchi depth, total phosphorus, and chlorophyll-a measured against Metropolitan Council thresholds. To suggest cleaner alternatives, we filter lakes within 30 miles to those with a strictly higher numeric score, then rank by grade improvement with a small proximity tiebreak. Cross-state and limited-data lakes are excluded so the list stays locally relevant.
