Why Gravel Lake has no grade
Gravel 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, Gravel Lake is Not Rated — not an F. Its 11.5-foot median from 124 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.
Gravel Lake is a 297-acre lake in Van Buren County, Michigan. Overall water quality is improving over recent sampling years. Limited fish-species data available. Public access is available with 1 public boat landing.
