Is Lej-08 Lake Polluted?
Yes — Lej-08 Lake in Allen County, Indiana is on the EPA's Clean Water Act 303(d) impaired-waters list (2024 assessment cycle). It is cited for Algal growth, Pathogens (E. coli, fecal), PCBs. No cleanup plan (TMDL) has been completed yet. "Impaired" is a legal designation, separate from the lake's A–F water-quality grade: it means at least one designated use (such as swimming, aquatic life, or fish consumption) does not meet state standards for the listed pollutant.

- Algal growth — listed by EPA as exceeding water-quality standards for at least one designated use.
- Pathogens (E. coli, fecal) — listed by EPA as exceeding water-quality standards for at least one designated use.
- PCBs — Polychlorinated biphenyls are legacy industrial pollutants that persist in sediment and bioaccumulate in fish. Like mercury, PCB listings drive fish-consumption advisories.

What this means for using Lej-08 Lake
Because Lej-08 Lake is listed for Pathogens (E. coli, fecal), swimming can be affected — check for posted beach advisories, especially after heavy rain or during visible algae. An impairment listing does not mean the lake is closed — most impaired lakes remain open for boating and swimming. It means a specific pollutant exceeds a standard for a specific use. Lej-08 Lake carries an overall water-quality grade of D, with algae (chlorophyll-a) at 24.1 µg/L — see the full breakdown on the lake report. The official EPA assessment is available in the ATTAINS waterbody report.
