Why Sanford Lake has no grade

Sanford 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, Sanford Lake is Not Rated — not an F. Its 17-foot median from 44 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.

Sanford Lake is a 53-acre lake in Benzie County, Michigan. Overall water quality is declining over recent sampling years. The lake supports 17 documented fish species including Black crappie, Blackside darter, and Bluegill.
