Why Newcomb Lake has no grade
Newcomb 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, Newcomb Lake is Not Rated — not an F. Its 11-foot median from 32 readings collected 2021–2022 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.
Newcomb Lake is a 40-acre lake in Montcalm County, Michigan. Overall water quality is improving over recent sampling years.
