Balsam Lake Little Balsam Site carries a Grade B (Good) water quality score. Within 30 miles, 4 lakes hold a higher grade. Half Moon Lake (Polk County, Grade A, 1.6 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.
