2011 Map of Devils Slide

About this map

South Fork Tolt Reservoir and its associated Tolt River Dam dominate the central landscape of this King County survey, reflecting the sophisticated water management systems required for the region's growth. The topography is defined by the steep descent of Devils Slide and the complex drainage of the North Fork Tolt River and North Fork Snoqualmie River systems. Within the protected North Fork Tolt Watershed, the map reveals a network of high-elevation water bodies including Lynch Lake and the smaller Lake Titicaca. Access to this terrain is limited to specialized routes like Tolt Reservoir Rd and various Forest Development roads such as NFD 210 Rd, which navigate the drainages of Deep Creek and Philippa Creek. Small mountain lakes like Black Lake and Mud Lake dot the southwestern corner, marking the headwaters of the Beaver Creek drainage.
