Hammond, J.C., 2020, Contiguous US and Global streamflow gages measuring zero flow: U.S. Geological Survey data release,


We report the site number and locations of 5798 streamflow gages displaying zero flow for at least one day in their daily records. 4891 of these gages are from the GRDC network, and 906 are USGS gages in the contiguous US. Additionally, provisional data for two USGS gages 1) Rio Puerco near Bernardo, NM (USGS site: 08353000) and 2) Agua Fria River Near Mayer, AZ (USGS site: 09512500) are provided to illustrate zero flow record behaviors.

Daily streamflow data was collected from existing GRDC and USGS gages sites to show the locations of gages that measure zero flow. Provisional data in unit value format for two USGS gages were obtained and are provided here to illustrate equipment error (USGS 08353000) and natural source loss (USGS 09512500). These data are provisional and subject to revision until they have been thoroughly reviewed and received final approval.
