Centennial Streamgages are USGS streamgages that have been in operation for more than 100 years.
USGS streamgaging began in 1889 with the establishment of the streamgage on the Rio Grande in Embudo, New Mexico, where the first team of hydrographers were trained in new techniques to measure water flow systematically.
Now, there are more than 12,000 USGS streamgages nationwide, 1,200 of which are Centennial Streamgages. In August 2025, we celebrated the 1,000th Centennial Streamgage.
A streamgage is like a bottle of wine—it gets better with age
Long-term streamgages provide valuable data for trend analysis, flood and drought prediction, and information for water supply, climate change, and land-use changes.
USGS streamgage data impacts the lives of everyone directly or indirectly—from the bridge you drive over, to the tap water that flows when you turn on your sink, to the production of food you eat each day.
