1953 Map of Boulder Lake Reservoir

USGS Topo · Published 1955

About this map

Cloquet Valley State Forest dominates this northern Minnesota landscape, reflecting a mid-century period focused on conservation and water resource management. Centered on the sprawling reaches of the Boulder Lake Reservoir, the map illustrates a complex hydraulic system managed by the timber and power interests of the era. The terrain transitions from the protected timberlands of the forest down toward the organized townships of Gnesen and Fredenberg in the south. The Us-Kab-Wan-Ka River flows through the northwestern corner, providing a glimpse into the original drainage patterns before the construction of massive reservoirs like Island Lake Reservoir. This survey provides researchers with a precise look at the shoreline at its 1950s elevations, including many unnamed islands and the specific forest boundaries that defined local land use.
