The Mississippi River spills more than 200 billion kilograms of sediment into the Gulf of Mexico each year, but the Rio Grande unloads a mere 730 million kilograms. Find out how much dirt other rivers and streams are toting, using this site from the U.S. Geological Survey. For nearly 1600 stations, the database provides daily measurements of suspended sediment, collected between 1930 and the mid-1990s. Although data for none of the stations span the full 60-plus years, many records run for more than 10 years and some more than 40.
