Kentucky Lake Water Quality

121 {{stateName}} lakes carry a grade. Most of the input data flows through monitoring run by {{agency}}, which feeds state, federal, and volunteer measurements into the EPA Water Quality Portal. A-grade lakes are scarce in {{stateName}}: about 8% of the dataset. Most lakes here sit in C or D — productive, often shallow, frequently algal in late summer.

Eutrophic conditions dominate — nutrient-loaded, productive, with algal pressure that shows up most years in late summer. These lakes tend to be shallow, agricultural-watershed, and over-warmed by the time July ends. The cleanest county on average is Russell (grade A); the most-stressed is Fulton. The gap between the top and bottom counties is large enough that "{{stateName}} lake water quality" hides real local variation.
