Cleaner Lakes Than Gator Lake Six Mile Cypress

Reading the cohort

Within 30 miles of Gator Lake Six Mile Cypress, 2 lakes score higher on EPA water-quality metrics than its Grade C. The short list means the alternatives are real upgrades but not interchangeable — each carries its own access, size, and species mix worth checking before substituting it into a weekend plan.

Lee-Harborage West Lake (Lee County, Grade B) is the closest cleaner option at 6.4 miles from Gator Lake Six Mile Cypress — close enough to be a genuine substitute for most users, far enough that it isn't the same neighborhood lake. Worth the trip if water quality is the primary driver; less obvious if Gator Lake Six Mile Cypress is on the way to other plans.

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.
