The page is rebuilt automatically every day from USGS's published data. Values can be revised later by the source agency.

Where does the data come from?

The U.S. Geological Survey's Water Data API (api.waterdata.usgs.gov), which publishes readings from USGS and partner gauges. Forecasts come from the National Weather Service.

Latest instantaneous reading; 7-day, 30-day and year-ago changes compare readings at the same hour. USGS data are provisional and subject to revision. This page is not affiliated with or endorsed by the USGS. See data sources.
