Swimming conditions
Readings onlyBacteria advisory
Based on clarity and algae readings from past sampling — there is no live water temperature and a current cyanobacteria reading for this lake. Check your state or county health department before you swim.
Nutrient and algae readings are not a swimming clearance. New Lexington Reservoir is listed impaired under Clean Water Act §303(d) (IR 5) for habitat alterations, metals (other than mercury), nutrients (phosphorus, nitrogen), oxygen depletion (low DO), pathogens (E. coli, fecal), pH / acidity, salinity / chlorides, sediment / turbidity. Check local advisories before you swim.
Whether New Lexington Reservoir is safe to swim in today is a call for the Ohio Environmental Protection Agency and the county health department, who post current advisories. LakeQuality does not issue swimming clearances.

Depth marked “est.” is a modeled maximum from GLOBathy (Khazaei et al. 2022, CC0), not a measured survey. Ohio has not published bathymetry for New Lexington Reservoir.
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.
