2019 Map of Boulder Lake Reservoir

About this map

Boulder Lake Reservoir and Island Lake Reservoir dominate this northern Minnesota landscape, where the managed waters of the Cloquet River and Otter River define the local topography. This 2019 survey captures the complex shoreline of these reservoirs, which are punctuated by numerous small islands and fingers of land like Breezy Point Rd. The intricate road network, including uniquely named ways such as Some Quiet Pl and Birch Isle Rd, suggests a region deeply tied to seasonal recreation and shoreline living. In the northern reaches, the Us-Kab-Wan-Ka River flows through more secluded terrain near Twin Lakes, while the southern portion of the map shows the structured dike system around the Island Lake Reservoir near N Dike Rd. This documentation of water management and rural access provides a clear view of the area's modern hydrological and transport patterns.
