2011 Map of Lake Shannon

USGS Topo · Published 2011

About this map

Lake Shannon dominates the northern landscape, its waters contained by the engineering of Bear Creek Dam and Baker Dam. This infrastructure, including the Bear Creek Powerhouse, reflects the region's long-standing reliance on hydroelectric power and water management. To the south, the Skagit River meanders through the valley, passing the settlements of Concrete and Van Horn. The map reveals a mix of industrial and residential development, with the streets of Concrete such as Railroad Ave and Main St providing a structured contrast to the high elevations of Jackman Ridge. Along the river, historical crossing points like Faber Ferry and smaller water bodies like Everett Lake provide evidence of how local transport and geography shaped these communities. The southern reaches are marked by rural roads like Concrete Sauk Valley Rd, connecting the scattered residential pockets of Mountview and beyond.
