General information

AccuWeather's River Gauge API delivers observational river data from across the United States, including water levels, flood-stage thresholds, action information, and low-water thresholds.

Data is returned as simplified JSON by default. Pass format=geojson to receive GeoJSON instead, or includeUnits=true to expand each measurement into value/unit/unitType triples.

→ See the River Gauge Guide and Parameters for endpoint details and request patterns.

River status

Every observation includes a categorical status describing the river's current flood condition. Each status has a corresponding color, returned both as RGB components and a hexadecimal value — useful for color-coded map overlays and dashboards.
