Where the record came from
The record came from Clear Lake in Steuben County. We don't carry a water-quality grade for it: our index covers standing lakes with enough EPA Water Quality Portal samples to score, which leaves out rivers and tributaries, Great Lakes water, and smaller ponds that are rarely sampled. Browse the Indiana lakes we do grade instead.
