Why Crystal Lake has no grade
Crystal 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, Crystal Lake is Not Rated — not an F. Its 10-foot median from 42 readings collected 2017–2022 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.
Crystal Lake is a 86-acre lake in Gogebic County, Michigan with a maximum depth of 25 feet. Overall water quality is improving over recent sampling years. The lake supports 16 documented fish species including Black crappie, Bluegill, and Burbot.
