Why Cranberry Lake has no grade
Cranberry 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, Cranberry Lake is Not Rated — not an F. Its 8.5-foot median from 78 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.
Cranberry Lake is a 24-acre lake in Oakland County, Michigan with a maximum depth of 25 feet. Water clarity is improving over recent sampling years. The lake supports 14 documented fish species including Black bullhead, Black crappie, and Blackchin shiner.
