Michigan Beach Advisories — Live E. coli & Algal Bloom Status
Beach advisories tracks Live list of Michigan beaches under advisory or closure for E. coli, sewage, or algal blooms. EGLE BeachGuard data updated daily. The reading is aggregated by Michigan Gateway from EGLE BeachGuard (Michigan Beach Monitoring Program), an authoritative public source, and refreshed automatically throughout the day.
For Michigan residents this indicator is one of several environmental-hazard signals that inform day-to-day decisions — from whether it's safe to be outdoors to whether a specific community needs additional attention. Combined with the other environment indicators listed at the bottom of this page, it helps residents, journalists, and county officials build a fuller picture of current conditions in Michigan.
The current reading for this indicator updates live on the
Michigan Gateway dashboard.
The data feed below is fetched from EGLE BeachGuard (Michigan Beach Monitoring Program) via the
public /api/beaches endpoint.
Michigan tests over 400 public beaches throughout the summer (May–September) for E. coli and algal toxins. A beach goes under advisory when E. coli exceeds 300 colonies per 100mL of water — that's the level the EPA links to a ~3.6% risk of gastrointestinal illness from swimming. A closure means contamination is severe enough that the beach is closed to the public.
- Before swimming, check the EGLE BeachGuard daily list for your beach.
- Avoid swallowing lake water — most bacterial risk is from accidental ingestion.
- Don't swim within 24-48 hours of heavy rain (storm runoff carries the most contamination).
- If you swim at an advisory beach and feel sick within 5 days, call your county health department.
