1953 Map of Boulder Lake Reservoir

USGS Topo · Published 1971

About this map

The Cloquet Valley State Forest dominates the northern reaches of this landscape, a heavily wooded region in St. Louis County shaped by mid-century water management. The primary focus is the sprawling Boulder Lake Reservoir, its irregular shoreline and numerous islands creating a complex aquatic environment for the townships of Gnesen and Fredenberg. To the south, the northern tip of the Island Lake Reservoir appears, indicating the interconnected nature of the regional drainage basin. Small natural water bodies like Nevens Lake, Apple Lake, and the Twin Lakes contrast with the larger reservoirs, while the Us-kab-wan-Ka River and Boulder Creek feed the system. This survey, updated with 1969 revisions, documents the forest boundary and the established water levels that defined this part of the Minnesota wilderness during the post-war era.
