North Umpqua River

Description

It rises in the high Cascades, issuing from Maidu Lake at elevation of 5998 ft in the Mount Thielsen Wilderness, along the Douglas-Klamath county line approximately 70 mi east of Roseburg. It follows a serpentine course down from the Cascades, westward along the southern side of the Calapooya Mountains. Its upper course passes through the Umpqua National Forest, past Toketee Falls and Steamboat, where it receives Steamboat Creek from the north. It receives the Little River from the south at Glide (the confluence is known as the Colliding Rivers) and joins the South Umpqua from the east approximately 5 mi northwest of Roseburg to form the Umpqua.

Facilities of the North Umpqua Hydroelectric Project are located along the river. It is impounded in its upper reaches in the Cascades to form Lemolo Lake for hydroelectricity. It is also impounded for hydroelectricity at Soda Springs Dam, forming a small reservoir on the upper river.

The river's reputation as a world-class steelhead stream and its famous emerald waters are a result of the fact the river source is high enough in the Cascades to derive from snowmelt during the entire year. The melting snow is trapped in volcanic soil and pumice and released during the summer months, providing an even cool-temperature flow. During the summer the flow of the river is approximately 20 times that of the nearby South Umpqua. In its lower reaches, the river's flow becomes increasingly erratic, in a manner typical of mountain streams of the region.

The region around the river has long been a timber-producing area. Starting in 1955, the watershed of the river was extensively clear cut, a practice which continued until 1969 when forestry management practices were changed. During this period many tributary streambeds were used as impromptu logging roads. The recovery of the river from these practices has been closely monitored by state and federal agencies.

Recreation

In 1988, the United States Congress designated 33.8 mi of the river between the Soda Springs Powerhouse and Rock Creek as wild and scenic under the National Wild and Scenic River program. Angling on this part of the river, frequented by salmon and steelhead, is limited to fly fishing.

On the North Umpqua, rafters and kayakers find whitewater challenges from Class I (easy) through IV (advanced) on the International Scale of River Difficulty from May through the summer months. The North Umpqua Trail, which runs parallel to the river, supports hiking and biking.

Tributaries

Named tributaries of the North Umpqua River from source to mouth are Tolo and Bradley creeks and Spring River, then Lake, Poole, White Mule, Warm Spring, Nancy, Beverly, Helen, Norma, Dorothy, and Sally creeks. Then Potter, Nurse, Barkenburger, Patricia, Alvin, Charlia, Loafer, and Deer creeks, followed by the Clearwater River and Fish, Medicine, Boulder, Eagle, and Copeland creeks.
