What this means
USGS stream gauges monitor river and stream levels across Michigan continuously. Each gauge has thresholds — Action Stage, Minor Flood, Moderate Flood, Major Flood — set by the National Weather Service for the communities downstream. When a gauge crosses Action Stage, low-lying property begins to flood.
What you can do
- If you live near a river that's at Action stage or higher, check the NWS Flood Watch / Warning page for your county.
- Sign up for free Wireless Emergency Alerts (WEA) on your phone — turn them on in Settings → Notifications → Emergency Alerts.
- Use https://water.weather.gov to see river forecast hydrographs (predicted crest height and time).
- Never drive through standing water — 6 inches can stall a car, 12 inches floats most vehicles.
