Why Leesville Lake has no grade
Leesville Lake has monitoring on record from two stations, 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, Leesville Lake is Not Rated — not an F. Its 5-foot median from 24 readings collected 2020–2021 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 Ohio EPA and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
Leesville Lake is a 1,000-acre lake in Carroll County, Ohio with an estimated average depth of about 71 feet. Limited fish-species data available. Public access is available with 3 public boat landings.

Depth marked “est.” is a modeled maximum from GLOBathy (Khazaei et al. 2022, CC0), not a measured survey. Ohio has not published bathymetry for Leesville Lake.
Lake Size & Watershed
Size, shoreline, and watershed area from HydroLAKES (HydroSHEDS). Mean depth here is modelled, not surveyed — HydroLAKES v1.0 estimates lake depth from surrounding terrain rather than from soundings. Treat it as an approximation, and prefer a state bathymetric survey where one exists.
