Swimming conditions

Readings only

Bacteria tested: low

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.

Bacteria testing record
from E. coli testing · 14 samples, 2 seasons

Based on E. coli testing, Browsout Lake never exceeded the EPA safe-swimming threshold (235 MPN/100mL) — on 0% of 14 samples across 2 seasons.

This is a historical summary of past testing, not a current condition — bacteria levels change quickly, especially after rain. Always check Florida’s current beach and health-department advisories before swimming.

Whether Browsout Lake is safe to swim in today is a call for the Florida Department of Environmental Protection and the county health department, who post current advisories. LakeQuality does not issue swimming clearances.
