Why Clark Lake has no grade
Clark 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, Clark Lake is Not Rated — not an F. Its 16.5-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.
Clark Lake is a 836-acre lake in Gogebic County, Michigan with a maximum depth of 74 feet. Overall water quality is declining over recent sampling years. The lake supports 1 documented fish species including Lake herring.
