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.
Based on E. coli testing, Tyner Lake never exceeded the EPA safe-swimming threshold (235 MPN/100mL) — on 0% of 29 samples across 8 seasons.
