USGS personnel at the Embudo Station, New Mexico
USGS prersonnel at the Embudo Station, New Mexico. Embudo was selected as the site of the first USGS streamgaging station in 1889 because of the need for systematic water resource assessments of western states as it not only offered a favorable climate and easy rail access, but qualified for congressional funding tapped specifically for the “arid West.”
