A study by the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers was conducted during the 2010 spring high-flow event to determine sediment con-centrations, loads, and particle-size distributions at six sites in the Red River of the North and selected tributaries near Fargo, North Dakota. Suspended-sediment (point and integrated samples), bed-material, and bedload samples were collected at the six sites at various time intervals during the high-flow event.
