| Abstract: | Suspended sediment samples have been collected by the U.S. Geological Survey from 115 sites on Minnesota streams since October 1960. Data from 42 sites were sufficient for characterizing sediment concentrations and yields. Average concentrations ranged from 4.4 mg/L on the Baptism River in northeastern Minnesota to 190 mg/L on the Root River in the southeast. Log-linear equations that describe the sediment transport curve were developed for 33 daily sediment stations and used to estimate long-term sediment yields. Average annual yields ranged from < 1.0 ton/sq mi on the Pelican River, to > 200 tons/sq mi on the Root and Whitewater Rivers and Deer Creek. Estimates indicated that under extreme circumstances the average annual sediment load for 2 years could be transported in slightly more than one day. Analysis showed that more than 90% of the annual sediment load was carried during 3 to 9 months of the year. On the average, almost 25% of the annual sediment load was transported during April. Generally, it was found that < 4% of the average annual load was transported during December, January, and February, which indicates that sampling frequency could be reduced during winter.
