Access Historical Instantaneous Streamflow Data with the New USGS Online Database
The IDA web site currently has about 1.5 billion instantaneous data values from 5,500 streamgages in 26 states. Populating this web site takes effort and resources that are being provided "as available," and not all states and streamgages are available at this time. The number of states and streamgages with data will continue to increase. It is possible that the IDA database will expand to include other variables such as temperature and pH in the future.
