1962 Map of Carter Lake Reservoir

About this map

Carter Lake Reservoir dominates this Larimer County landscape, its western shores flanked by several quarries and the sharp rise of the foothills. This post-war era map documents the complex water management infrastructure essential to the region's agricultural and power needs. Significant engineering works include the Flatiron Powerplant and its associated Flatiron Reservoir, connected by a network of penstocks and a pressure tunnel. To the east, the terrain transitions into an intricate web of irrigation ditches and smaller catchments like Lonetree Reservoir and Hertha Reservoir. The Little Thompson River winds across the southern portion of the sheet near the border of Larimer and Boulder Counties, while old routes like the Pack Trail suggest earlier modes of travel through Chimney Hollow.
