2022 Map of Boulder Lake Reservoir
USGS Topo · Published 2022About this map
Boulder Lake Reservoir and the northern reaches of Island Lake Reservoir dominate this watery landscape in St. Louis County. The area is defined by its complex hydrography, where the Cloquet River and Otter River feed into these expansive reservoirs. Small tributaries like Boulder Cr and the uniquely named Us-Kab-Wan-Ka River drain the surrounding timberlands, while isolated bodies of water such as Twin Lakes and Apple Lake dot the wetlands.
