1994 Map of Detroit

About this map

The North Santiam River and its impoundment at Detroit Lake dominate this mid-1990s landscape at the border of Linn and Marion counties. Centered on the town of Detroit, the map reveals a region defined by hydroelectric infrastructure and timber management, featuring the Detroit Dam, a Diversion Dam, and a Substation near the river’s original course. The topography is characterized by steep ridges like Kinney Ridge and Halls Ridge, falling away to the deep waters of the lake where recreational features such as Piety Island and various boat ramps are established. Much of the surrounding land is divided between the Santiam State Forest and the Willamette National Forest, with industrial activity marked by several Quarry sites and a Heliport indicating the logistical needs of this mountainous timber and water corridor.
