Contiguous US and Global streamflow gages measuring zero flow 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.

These images were collected for the purpose of evaluating UAS assessment of river habitat data such as water depth, substrate type, and water clarity. Each UAS was equipped with a Ricoh GRII digital camera for natural color photos, used to produce digital elevation models and ortho images, a MicaSense RedEdge multi-spectral camera that captures five specific bands of the visible spectrum (blue, green, red, rededge, and near-infrared), which can be used to classify vegetation, or FLIR Vue Pro R 640 13mm radiometric thermal camera that provides temperature data embedded in every...
