Why Devils Head Lake has no grade

Devils Head 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, Devils Head Lake is Not Rated — not an F. Its 9-foot median from 3 readings collected 2017–2023 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 EGLE and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.

Devils Head Lake is a 92-acre lake in Gogebic County, Michigan with a maximum depth of 47 feet. Overall water quality is declining over recent sampling years. Limited fish-species data available. Public access is available.
