Why Bass Lake has no grade
Bass 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, Bass Lake is Not Rated — not an F. Its 11.8-foot median from 8 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.
Bass Lake is a 76-acre lake in Marquette County, Michigan with a maximum depth of 78 feet. The lake supports 10 documented fish species including Bluntnose minnow, Brook stickleback, and Creek chub. Public access is available with 1 public boat landing.
