USGS streamgagers, Mike Sanders and Henry Sanger are servicing the, Salt River near Roosevelt, Arizona streamflow gaging station and making a streamflow measurement on January 22, 2010. Flow was measured to be 44,500 cubic feet per second (CFS) on the 22th but peaked earlier on the 22nd at an estimated 88,000 cfs.

USGS employees, John Hoffmann, Corey Salmond, Robert Fritzinger, and Chris Smith are being interviewed by Naomi Pescovitz from KVOA on January 22, 2010. Robert Fritzinger and Corey Salmond are making a streamflow measurement at Rillito Creek at La Cholla BLVD near Tucson streamflow gaging station.

USGS streamgagers make a low flow measurement on the San Pedro River at Charleston.

As part of the assessment of the binational San Pedro aquifer, the effects of urbanization on runoff in ephemeral streams was studied. Ephemeral streams are those that flow in response to precipitation. Runoff in tributaries to the San Pedro River is important in understanding the water budget of the river.
