Umpqua River Oregon Garden Valley PhotoMosaic 1939
Description
The Umpqua River drains 12,103 square kilometers (4,673 square miles) in southwest Oregon before flowing
into the Pacific Ocean at Winchester Bay near the city of Reedsport. In cooperation with the Portland District
of the U.S. Army Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage
along the downstream alluvial reaches of the North and South Umpqua Rivers and the entire mainstem Umpqua
River. This includes the lower 46.8 kilometers (29.1 miles) of the North Umpqua River and the lower 122.6
kilometers (76.2 miles) of the South Umpqua River.
The Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical
channel change and estimation of a sediment budget. To support these analyses, digital channel maps were
produced to depict channel and floodplain conditions along the Umpqua River system from different time periods.
