2011 Map of Lake Joy

About this map

Lake Joy and Moss Lake sit at the heart of this landscape, reflecting the hydrological management of King County's water resources. The area is defined by the complex convergence of the Tolt River and its major tributaries, including the North Fork Tolt River and South Fork Tolt River. Evidence of industrial and utility infrastructure is found at Swans Mill Pond Dam and the substantial Tolt Regulating Basin, which is secured by the Tolt River Regulating Basin West and South Dams. While much of the terrain is dominated by the drainages of Griffin Creek, Canyon Creek, and Tokul Creek, the higher elevations are marked by the Snoqualmie Lookout. The road network, including Swan Mill Rd and NE Moss Lake Rd, provides access to these isolated water bodies and the forested tracts between them.
