What is the cleanest lake near Lake Mango North?

Hillsborough-June Lake in Hillsborough County holds a Grade C water quality score and is 1 miles from Lake Mango North.

Why is Lake Mango North not Grade A?

Lake Mango North holds Grade F, with about 1.5 ft of water clarity and 114 µg/L of phosphorus. The grade reflects measured water quality against Metropolitan Council thresholds. Cleaner alternatives nearby score higher on clarity, phosphorus, or chlorophyll-a.

Are these recommendations based on real data?

Yes. Every grade is calculated from EPA Water Quality Portal samples for the lake. Recommendations are limited to lakes within 30 miles of Lake Mango North in Florida, with strictly higher numeric grade scores and sufficient monitoring data.

Reading the cohort

Only 3 lakes within a 30-mile radius score better than Lake Mango North's Grade F. The narrow set of options reflects either a fairly clean lake to begin with or a region without a wide range of cleaner alternatives — the trip-planning decision is more constrained than the headline "cleaner lakes nearby" suggests.

The closest cleaner alternative — Hillsborough-June Lake in Hillsborough County, Grade C — sits 1 miles from Lake Mango North. At that distance, the substitution cost is essentially zero: same drive time, same regional access, demonstrably cleaner water on the EPA indicators. For repeat visitors who care about clarity or phosphorus levels, swapping the routine to Hillsborough-June Lake is mostly a habit change rather than a logistics change.

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.
