Why Leatherwood Lake has no grade
Leatherwood 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, Leatherwood Lake is Not Rated — not an F. Its 7-foot median from 3 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 ADEQ and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
Leatherwood Lake is a 85-acre lake in Carroll County, Arkansas. Overall water quality is improving over recent sampling years.
