1 higher-graded lake within 30 miles, ranked by grade improvement and proximity.
Indian Lake carries a Grade D (Poor) water quality score. Within 30 miles, 1 lake holds a higher grade. Lake Mendota (Dane County, Grade B, 12.3 mi away) is the closest meaningful upgrade.
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.
