USGS publishes an up-to-date streamflow report for Missouri rivers on its official website. USGS is the United States Geological Survey authority. Its streamflow reports show gage height measurements taken at regular times throughout the day.
The USGS website provides updated streamflow reports for Missouri rivers indicating their current water levels. Data for daily water level averages is also available in individual graphs that show gage heights fluctuations for each day of the week and for each river. Anyone interested in older data can also use an internal search engine feature to find historical water level information. USGS stations monitor Missouri's main rivers, such as the Missouri River, the Grand River and the Blue River.
