About the south umpqua river


The South Umpqua River is a 115-mile-long river in southwestern Oregon, United States. The river was named after the Umpqua tribe of Native Americans who inhabited the area. The headwaters of the river are located in the Cascade Range, and it flows into the Pacific Ocean near Reedsport. The river is a major tributary of the Umpqua River. The hydrology of the river is highly regulated by several dams and reservoirs, including the Galesville Reservoir, the Tiller Reservoir, and the South Umpqua Falls Reservoir. These reservoirs serve various purposes, including hydroelectric power generation, irrigation, and flood control. The South Umpqua River is also a popular destination for recreational activities such as fishing, camping, and boating. The river's waters are used for agricultural purposes, including the cultivation of berries and orchards.
