1988 Map of Bumping Lake

USGS Topo · Published 1989

About this map

Bumping Lake and its surrounding high-elevation landscape are documented here as they appeared in the late 1980s. The reservoir, regulated by Bumping Dam with a spillway elevation of 3,426 feet, serves as a central hub for activity within the Snoqualmie National Forest. The map illustrates a network of recreational sites, including the Bumping Lake Campground, a Picnic Area, and various boat facilities. A flume and the winding Bumping River provide insight into the local water management and drainage patterns that define this valley.
