The U.S. Geological Survey began collecting streamflow information in 1889, when the first stream-gaging station was established on the Rio Grande River near Embudo, New Mexico.
Personnel from the Irrigation Survey, which was then a branch of the U.S. Geological Survey, were directed by John Wesley Powell to develop procedures that could be used to produce reliable streamflow estimates. Powell felt that it was important to inventory the flow of streams in the arid west prior to settlement.
