Why Keuka Lake has no grade
Keuka 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, Keuka Lake is Not Rated — not an F. Its 23.6-foot median from 8 readings collected 2020 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 NYSDEC and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
Keuka Lake is a lake in Yates County, New York with an estimated average depth of about 65 feet. Limited fish-species data available. Public access is available with 1 public boat landing.
