Why Maceday Lake has no grade
Maceday 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, Maceday Lake is Not Rated — not an F. Its 14-foot median from 57 readings collected 2016–2022 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.
Maceday Lake is a 210-acre lake in Oakland County, Michigan with a maximum depth of 117 feet. Overall water quality is declining over recent sampling years. The lake supports 1 documented fish species including Lake herring.
