Why Ocoee River Lake has no grade
Ocoee River 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, Ocoee River Lake is Not Rated — not an F. Its 14.2-foot median from 7 readings collected 2012–2026 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 TDEC and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
Ocoee River Lake is a 1,620-acre lake in Polk County, Tennessee. Limited fish-species data available. Public access is available with 2 public boat landings.
