Why Wormer Lake has no grade
Wormer 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, Wormer Lake is Not Rated — not an F. Its 10-foot median from 19 readings collected 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.
Wormer Lake is a 370-acre lake in Oakland County, Michigan with a maximum depth of 24 feet. Overall water quality is improving over recent sampling years. Limited fish-species data available. Public access is available.
