The river flows through the Cascade Range and is fed by numerous tributaries. The river has two major reservoirs, Detroit Lake and Big Cliff Reservoir, both of which were built in the mid-20th century for hydroelectric power generation and flood control. The North Santiam River is also used for recreational activities such as fishing, kayaking, and swimming. The river is home to a variety of fish species, including Chinook salmon, steelhead trout, and rainbow trout. The surrounding agricultural land is irrigated with water from the river, making it an important resource for the local farming communities.

Historical River Levels

The North Santiam River is a 92-mile (148 km) tributary of the Santiam River in western Oregon in the United States. It drains 766 square miles (1,980 km2) of the Cascade Range on the eastern side of the Willamette Valley east of Salem.It rises in the high Cascades in eastern Linn county, northwest of Three Fingered Jack in the Willamette National Forest. It flows north through the mountains past Marion Forks, receiving the drainage from the western slope of Mount Jefferson. Near Mount Jefferson it turns sharply west, descending through a canyon past Idanha and Detroit to Niagara County Park where the valley begins to widen and some agriculture use begins. Continuing west, the river flows past Gates, Mill City and Mehama. It emerges through the foothills into the Willamette Valley near Stayton, then flows 15 miles (24 km) southwest through the valley where it joins the South Santiam River to form the Santiam River. The confluence is approximately 10 miles (16 km) east of the confluence of the Santiam and the Willamette River.
It is impounded by Detroit Dam in the mountains west of Detroit to form Detroit Lake for flood control. Detroit Lake State Park is along the northern shore of the lake.
In the 19th century, the canyon of the North Santiam River provided a formidable obstacle to settlers. The construction of a railroad in 1887 opened up the canyon to settlement and logging of the surrounding mountains.
