USGS hydrographer Spencer Wheeling gets equipment ready to collect a flood water-quality sample on the Wild Rice River near St.

USGS hydrographer Brent Hanson wades out in freezing waters to collect flood measurements on the Sheyenne River near Cooperstown, North Dakota. Hanson reads an outside staff, which is a vertical graduated ruler used to calibrate the continuous readings of water level provided by electronic sensors.

USGS employee Spencer Wheeling is forced to get creative on April 5, 2020, in the positioning of the crane used for collecting water-quality samples thanks to 6-8 inches of new snow at station 05053500 Wild Rice River near St. Benedict, ND.

A frozen USGS rapid deployment streamgage measures the height of the Maple River near Page, North Dakota. RDGs can be installed on short notice to provide additional information at locations that are normally not gauged.

Hydrologic Technician Sharon Mulready checks equipment on electrical power tower and site 372750122012701 Coyote Creek near Alviso Slough. The tidal gage is located at the confluence of Coyote Creek and Alviso Slough, and is accessible only by boat. The estuary is fed by the Sacramento and San Joaquin Rivers, and various tributaries in the Central Valley.
