1953 Map of Boulder Lake Reservoir

About this map

Cloquet Valley State Forest dominates the northern reaches of this mid-century survey, where the Us-Kab-Wan-Ka River feeds into a landscape heavily shaped by hydraulic engineering. The topography is defined by the expansive Boulder Lake Reservoir at a normal elevation of 1391 feet, and the northern edge of the Island Lake Reservoir to the south. These artificial water bodies, characterized by their intricate, island-studded shorelines, contrast with the smaller natural basins of Twin Lakes and Nevens Lake. The boundary between the townships of Gnesen and Fredenberg is clearly delineated near the southern reservoir, providing a precise record of local civil divisions during the early 1950s. Boulder Creek winds through the eastern timberlands, illustrating the drainage patterns that support this managed watershed in St. Louis County.
