Michigan Flood Gauges — Live USGS River Levels

Flood gauges tracks Real-time flood-stage status for 200+ USGS stream gauges across Michigan watersheds. See which rivers are at action, minor flood, or major flood stage right now. The reading is aggregated by Michigan Gateway from U.S. Geological Survey (USGS), 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 U.S. Geological Survey (USGS) via the public /api/gauges endpoint.

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.
