Why Tippecanoe Lake has no grade
Tippecanoe Lake has monitoring on record from one station, but only water clarity was measured. LakeQuality’s A–F letter uses total phosphorus, total nitrogen, chlorophyll-a, and turbidity against EPA National Lakes Assessment condition classes. With none of those grading measurements on record, Tippecanoe Lake is Not Rated — not an F. Its 8.5-foot median from 11 readings collected 2021 is still shown as clarity, but clarity alone cannot earn a letter.
Not Rated is EPA Integrated Reporting Category 3 — insufficient information. Everything below that has been measured is still reported on this page.
Sampling is run by IDEM and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
